217 + + + 14 + + + +Introduction +PowerWorld has incorporated the ability to import data to/from data sources other than power flow models into +PowerWorld Simulator. The text file interface for exchanging data, as well as for executing a batch script command, is +represented by the auxiliary files. The script language and auxiliary data formats are incorporated together. This format is +described in this document. + +Script/Data files are called data auxiliary files in Simulator and typically have the file extension .AUX. These files mostly +contain information about power system elements and options for running the various tools within Simulator. They do +not contain any information about the individual display objects contained on a one-line diagram. There are separate files +called display auxiliary files that are available for importing display data to/from Simulator in a text format. These files are +distinguished from the data auxiliary files by using the extension .AXD. The format for these two types of files is similar, +but different object types are supported by each and require that the files be read separately. + +Both file types will be generically referred to as auxiliary files. An auxiliary file may be comprised of one or more data or +script sections. A data section provides specific data for a specific type of object. A script section provides a list of script +actions for Simulator to perform. These sections have the following format: + + +SCRIPT ScriptName1 +{ +script_statement_1; + . +script_statement_n; +} + +object_type DataName1(list_of_fields) +{ +data_list_1 + . +data_list_n +} + +object_type DataName2(list_of_fields) +{ +data_list_1 + . +data_list_n +} + +SCRIPT ScriptName2 +{ +script_statement_1; + . +script_statement_n; +} + + +Data sections start with the string representing the object_type, but older auxiliary files start with the syntax +DATA DataName(object_type, [list_of_fields]) +See the description of the data section later in this document for more information. + +Note that the keywords script, data, or a valid object_type must occur at the start of a text file line. Auxiliary files may +contain more than one section. These sections always begin with the keyword script, data, or a valid object_type. Data +sections are followed by an argument list enclosed in ( ). The actual data or script commands are then contained within +curly braces { }. Strings are enclosed in straight quotes – note that smart quotes will not work (this might be encountered +when copy/pasting script commands from another program). The Script commands available are described in the next +main section. The data sections are then described after this. There are separate sections for describing the data sections +for the data auxiliary files and the display auxiliary file. + + 15 + + + +SCRIPT Section +SCRIPT ScriptName +{ +script_statement_1; + . +script_statement_n; +} + +Scripts may optionally contain a ScriptName. This enables you to call a particular SCRIPT by using the LoadScript action +(see General Actions). After the optional name, the SCRIPT section begins with a left curly brace and ends with a right +curly brace. Inside of this, script statements can be given. In general, a script statement has the following format + + +Keyword(arg1, arg2, ...); +• Statement starts with a keyword. +• The keyword is followed by an argument list which is encompassed in parentheses ( ). +• The arguments are separated by commas. +• If a single argument is a list of things, this list is encompassed by braces [ ]. +• Statements end with a semicolon. +• Statements may take up several lines of the text file. +• You may put more than one statement on a single text line. + + +Those familiar with using Simulator will know that there is a RUN and EDIT mode in Simulator. Some features in Simulator +are only available in one mode or the other. This functionality will be preserved in the script language. In earlier versions +of the software, certain functionality was organized by the "submode" feature. While existing scripts designed to work +with submodes will still function as before, moving between submodes is no longer necessary. + +Various script commands require that you be in RUN or EDIT mode. If a script requires this, then the script will +automatically change modes. + +Using Filters in Script Commands +Many script commands allow the specification of a filtername. Only those objects meeting this filter will be selected for +the specified action. Unless otherwise specified, a blank filter will select all objects. This filtername can be the name of an +advanced filter. The filtername should be enclosed in double quotes. Advanced filters belonging to a different objecttype +can also be used depending on the objectype in use. For example, if filtering generator objects a bus filter can also be +used. When using an advanced filter that belongs to a different objecttype, the format of the filter is +"filtername" instead of just specifying the filtername itself. + +The filtername can also be the name of a device filter. A device filter allows you to specify a particular object for filtering +instead of a class of object. For example, you might want to return all buses that belong to a particular substation. You +can specify the device filter for the particular substation and then apply this to the bus objects. The format of a device +filter is "objecttype 'key1' 'key2' 'key3'". + +In addition to a filtername, special keywords can be used to indicate the type of filter desired. These include the following: + +AREAZONE : Only objects that meet the area/zone/owner filters will be selected for the specified action. +SELECTED : Only objects whose Selected field is YES will be selected for the specified action. + + +(Added in October 5, 2023 patch of Simulator 23) FilterName may also be a special string with the syntax such as +"MW >= 50" representing a single-condition filter. The syntax is Variablename Comparison Value1 Value2. These +special single-condition filters are convenient to use because there is no need to create a new filter object, and instead +one is created inside the software for temporary use. Examples for a Bus would be the following: +"NomkV between 220 550" +"MW >= 50" + + 16 + + + +Specifying Special Keywords in Script Command Parameters +There are special keywords that may be used as part of the input for script command parameters. Generally, these are +allowed as part of the file name input in commands that save or modify files, as well as some other commands that take +text as input. These special keywords will be replaced with their actual values when the script command is processed. + +The special keywords that are allowed and their associated replacement strings are shown in the following table: + + +@BUILDDATE Simulator patch build date +@CASEFILENAME File name of the presently open case. This is only the file name without the path. +@CASEFILEPATH Directory path of the presently open case +@CASENAME Name of the presently open case including the path and file name +@DATE Present date +@DATETIME Actual date and time in the format yyyymmdd_hhnnss-hhmm with the UTC offset + +included on the end of the time +@TIME Present time +@VERSION Simulator version number + + +The special keyword @MODELFIELD can be used in combination with an object type and variable name so that any field of +any object can be included in the text. The syntax for inserting the value of a model field in the text is the following: +@MODELFIELD. + +Specifying File Names in Script Commands +In place of the "filename" parameter in any script command, specially formatted text can be used to indicate that the user +should be prompted to choose the file. Depending on whether or not a file is being opened or saved, an Open or Save +dialog will be presented for the user to choose the file. This will not work when using the SimAuto Add-on. + +The special syntax of the filename parameter is generally: +"" +The entire string must start with . The parameters after PROMPT are all optional, must be space +delimited, must be enclosed in single quotes, and can be specified as follows: + Caption + +Caption to be placed at the top of the file dialog that appears. If omitted, either 'Save' or 'Open' is assumed +based on how the prompt is used to access a file. + + FileTypes +List of file types and extensions. The list itself is composed of a pipe-delimited string (|) with the first string +representing the first file type, the second string representing the first file extension, the third string +representing the second file type, the fourth string representing the second file extension and so on. If no file +types are specified, 'All Files (*.*)|*.*' is assumed. + + InitialDirectory +The initial directory in which the dialog should open. + + CancelAction +The CancelAction can either be 'Abort' or 'Continue', with 'Abort' being the default. If the Cancel button is +clicked on the resulting dialog, the CancelAction specifies how to proceed. Setting this to 'Abort' will skip the +command and abort any remaining auxiliary file commands. Setting this to 'Continue' will skip the command +but continue processing the remaining auxiliary file commands. + + +Here is an example prompt using all options: +"" + +The special keywords described in the Specifying Special Keywords in Script Command Parameters section can also be +used as part of a filename. + + 17 + + + +Specifying Field Variable Names in Script Commands +See the Field Variable Naming (Legacy) topic in the DATA Section for general information about naming fields. + +Within select script commands the keyword ALL can be used instead of using the location number of a field when +specifying variable names as part of a field list. This will return all fields with the same variable name. This is intended to +allow easier access to fields when the exact number of fields is not known, such as with multiple TLR (MultBusTLRSens:ALL) +or PTDF (LinePTDFMult:ALL) results. This can be used with SaveData, SaveDataWithExtra, SaveObjectFields, and +SendToExcel script actions. + +Within select script commands the keyword ALL can be used instead of a list of fields. This will return all fields for a +particular objecttype. This can be used with SaveData, SaveDataWithExtra, SaveObjectFields, and SendToExcel script +actions. + +Within these same Save related script commands for any transient stability data model objecttype (Machines, Exciters, +etc…), the special strings may be used to export all the model input parameters for the stability model and the various +primary, secondary or label key fields. These special strings are as follows. + +AllModelParams exports all the model input parameters and references to objects necessary to define +model + +AllModelParamsPriKey exports the primary keys for the objecttype and the same fields as AllModelParams +AllModelParamsSecKey exports the secondary keys for the objecttype and the same fields as AllModelParams +AllModelParamsLabel exports the label key for the objecttype and the same fields as AllModelParams + + + +Specifying Field Values in Script Commands +Several script commands require that a valuelist be specified to assign values to a corresponding fieldlist. Instead of +specifying the values explicitly, special formatting is available to assign values from other fields. See the Special Data List +Entries topic in the DATA Section for more information. + + + 18 + + + +AUX Actions +General Program Actions + +CopyFile("oldfilename", "newfilename"); +Use this action to copy a file from within a script. + +"oldfilename" : The present file name. See the Specifying File Names in Script Commands +section for special keywords that can be used when specifying the file +name. + +"newfilename" : The new file name desired. See the Specifying File Names in Script +Commands section for special keywords that can be used when +specifying the file name. + + +This command duplicates the file named “B7FLAT.pwb” and saves the copy as +“B7FLAT_BACKUP.pwb” in the same directory. +CopyFile("B7FLAT.pwb", "B7FLAT_BACKUP.pwb"); + +DeleteFile("filename"); +Use this action to delete a file from within a script. + +"filename" : The file name to delete. See the Specifying File Names in Script +Commands section for special keywords that can be used when +specifying the file name. + + +This call deletes the file named “B7FLAT_BACKUP.pwb”. +DeleteFile("B7FLAT_BACKUP.pwb"); + +ExitProgram; +Immediately exits the program with no prompts. Note that this command should not be used in scripts +loaded through SimAuto, as the SimAuto instance should be managed from the script which created it. + +LogAdd("text"); +Use this action to add a personal message to the Message Log. + +"text" : The text that will appear as a message in the log. + + +This command adds the greeting “hello” in the message log. +LogAdd("hello"); + +LogAddDateTime("label", includedate, includetime, includemilliseconds); +Use this action to add the date and time to the message log + +"label" : A string which will appear at the start of the line containing the +date/time. + +includedate : YES – Include the data or NO to not include. +includetime : YES – Include the time or NO to not include. +includemilliseconds : YES – Include the milliseconds or NO to not include. + + +This command adds a log entry labeled "DateTime" to the message log, including the current +date, time, and milliseconds. +LogAddDateTime("DateTime", YES, YES, YES); + +LogClear; +Use this action to clear the Message Log. + + 19 + + + +LogSave("filename", AppendFile); +This action saves the contents of the Message Log to "filename". + +"filename" : The file name to save the information to. +AppendFile : Set to YES or NO. YES means that the contents of the log will be + +appended to "filename". NO means that "filename" will be overwritten. + + +This command saves the current contents of the Message Log to a file named "LogFile1", +overwriting any existing data in that file. The NO parameter ensures that the file is replaced rather +than appended to. +LogSave("LogFile1", NO); + +LogShow(DoShow); +This action will show or hide the Message Log. + +DoShow : Set to YES to show the Message Log. Set to NO to hide the Message +Log. + +RenameFile("oldfilename", "newfilename"); +Use this action to rename a file from within a script. + +"oldfilename" : The present file name. See the Specifying File Names in Script Commands +section for special keywords that can be used when specifying the file +name. + +"newfilename" : The new file name desired. See the Specifying File Names in Script +Commands section for special keywords that can be used when +specifying the file name. + + +This command renames the file "results_old.csv" to "results_final.csv". +RenameFile("results_old.csv", "results_final.csv"); + +SetCurrentDirectory("filedirectory", CreateIfNotFound); +Use this action to set the current work directory. + +"filedirectory" : The path of the working directory. See the Specifying Special Keywords +in Script Command Parameters and Special Identifiers for Model Fields +section for information on special keywords that can be used as part of +the directory name. + +CreateIfNotFound : Set to YES or NO. YES means that if the directory path cannot be +found,the directory will be created. If this parameter is not specified, NO +is assumed. + +StopAuxFile; +Use this action to treat the remainder of the file after the command as a big comment. This includes any +script commands inside the present SCRIPT block, as well as all remaining SCRIPT or DATA blocks. + +WriteTextToFile("filename", "text"); +Use this action to write text to a file. If the specified file already exists, the text will be appended to the +file. Otherwise, it creates the file and writes the text to the file. + +"filename" : The file path and name to save. +"text" : The text to be written to the file. Special keywords can be entered that + +will be replaced with their actual values. These include @BUILDDATE, +@DATETIME, @DATE, @TIME, @VERSION, and @CASENAME. + + + + + 20 + + + +Data Interaction +CustomFieldDescriptionAppend(ObjectType, CustomType, FieldString, HeaderString, IncludeInDiff); + +(This command was added in the December 4, 2023 patch of Simulator 23) +This command behaves the same as calling CustomFieldDescriptionModify but the Location is assumed to +be a negative number. This creates a new CustomFieldDescription by incrementing the +CustomMaxOfType. + +CustomFieldDescriptionModify(ObjectType, CustomType, Location, "FieldString", "HeaderString", +IncludeInDiff); + +(This command was added in the December 4, 2023 patch of Simulator 23) +Use this script command to edit the CustomFieldDescription entries for a particular +ObjectType/CustomType/Location. + +ObjectType : The object type to which the Custom Field Description is applied +CustomType : Either Integer, String or Floating Point +Location : Integer value for the location number of the custom field. Entering a + +negative value for Location will increment the present CustomMaxOfType +by 1 for the present ObjectType/CustomType and this newly added entry +will be edited by the command. Remember that "Custom Integer 4" +corresponds to CustomInteger:3 and for that example you would use a +Location of 3. If a location is chosen that is too large, then the +CustomMaxOfType will be increased to accommodate the location. + +FieldString : String shown when field is displayed. Remember that a \ results subfolder +being created under the Custom folder. Enter a value of "_same_" if you +do not want to change the string. + +HeaderString : String shown in column headers in case information displays. Enter a +value of "_same_" if you do not want to change the string. + +IncludeInDiff : This specifies if the field is included in Difference Case comparisons. Set +to YES, NO, or "", where a blank indicates that the value is not changed. + + +This command modifies the description of a custom string field at location 3 for bus objects. The +location numbers are zero-indexed meaning that location 3 refers to the fourth custom string +field. This sets the internal field name to "Custom_Region_v2", the header displayed in case info +to "Updated_Region_Label", and enables inclusion in difference case comparisons (YES). +CustomFieldDescriptionModify(BUS, String, 3, "Custom_Region_v2", +"Updated_Region_Label", YES); + +CreateData(objecttype, [fieldlist], [valuelist]); +Use this action to create particular objects. + +objecttype : The objecttype being created. +[fieldlist] : A list of fields to set with the object. The key fields and required fields + +must be specified. +[valuelist] : A list of values corresponding to the respective fields. + + +This command creates a new Bus object in the case with the specified attributes. The bus is +named "Eight", assigned the number 8, placed in Area 1 and Zone 1, and given a nominal voltage +of 138.00 kV. +CreateData(BUS, [Name, Number, AreaNumber, ZoneNumber, NomkV, +NameNomkV], [Eight, 8, 1, 1, 138.0, Eight_138.0]); + + + + 21 + + + +Delete(objecttype, filter); +Use this delete objects of a particular type. A filter may optionally be specified to only delete objects that +meet a filter. + +objecttype : The objecttype being selected. +filter : Optional parameter – default is to delete all objects of specified type + See Using Filters in Script Commands section for more information on + +specifying the filter. + + +This command deletes all Buses where the Selected field is YES. +Delete(BUS, SELECTED); + +DeleteDevice([ObjectIDString]); +Use this action to delete a specific object. + +[ObjectIDString] : The specific object to delete. The format is the object type followed by +the key fields used to identify the object. Examples: DeleteDevice([Bus +234891]), DeleteDevice([Branch 1239 1234 "AB"]), and +DeleteDevice([Interface "my interface name"]). + + +This command deletes Bus 1. +DeleteDevice([Bus 1]); + +DeleteIncludingContents(objecttype, filter); +Use this to delete objects of a particular type and other objects that these contain. Currently, only multi- +section lines (objecttype = MultiSectionLine) can be used with this command. The branches and dummy +buses that belong to multi-section lines will also be deleted along with the multi-section lines. A filter may +optionally be specified to only delete objects that meet a filter. The syntax is identical to the +Delete(objecttype, filter); action above. + + +This command deletes all multi section lines along with the branches and dummy buses +associated with them. +DeleteIncludingContents(MultiSectionLine,); + +ExportAreaSupplyCurves("filename", "User Defined String", NumPoints); +Use this action to export Area Supply Curves to a CSV file. The output of the file will have 7 entries for +each area for Fixed Gen MW, Fixed Load MW, Fixed Shunt MW, Losses MW, Variable Min MW, Variable +Max MW, Variable Present MW, followed by a set of Bid MW/Price entries represents the supply curve for +the variable MWs. + +"filename.csv" : The name of the CSV file to which results will be written. +"User Defined String" : This is an optional parameter for specifying a user defined string written + +to each entry in the resulting CSV file. If this is omitted, blank will be +assumed. + +NumPoints : This is an optional parameter and is related to converting a cubic cost +model into a piece-wise linear model. If this is omitted, 5 is the default. + + +This command exports area supply curve data to the file TestAreaSupply.csv, tagging each entry +with "ScenarioA" and using 20 points to linearize the variable MW cost curves. The output +includes fixed generation, load, shunt values, losses, and a detailed bid-based supply curve for +each area. +ExportAreaSupplyCurves("TestAreaSupply.csv", "ScenarioA", 20); + + + + 22 + + + +ImportData("filename", FileType, HeaderLine, CreateIfNotFound); +Use this action to import data in various file formats that are not native to Simulator. +"filename" : Name of the file to import +FileType : Parameter that specifies the format of the data this is being read. + +Currently supported are two methods of importing CROW files as created +by the Equinox Control Room Operations Window application. This is +used with the Scheduled Actions add-on tool. + +CSV : Uses CSV Import Settings as specified in the Scheduled +Actions dialog to read in a CROW CSV file. + +PWCSV : Uses the PowerWorld Outage CSV format. +CROW : Uses the hardcoded format Scheduled Actions was originally + +programmed to import. +HeaderLine : Optional parameter to specify if the row of headers in the CSV file is on + +the first line (1) or second line (2). If left blank (or any other value is +specified), it will use the setting last configured in the Scheduled Actions +dialog. + +CreateIfNotFound : Optional parameter that is NO by default. Set this to YES to create +objects defined in the data if they do not already exist. + + +This command imports data from the file "GenFields.csv" using the CSV format. It assumes the +header row is on the first line of the file and will create any new objects from the data if they +don't already exist in the case. +Importdata("GenFields.csv", CSV, 1, YES); + +LoadAux("filename", CreateIfNotFound); +Use this action to load another auxiliary file from within a script. + +"filename" : The filename of the auxiliary file being loaded. +CreateIfNotFound : Optional – default is NO when using the Legacy Auxiliary File Header + +format. Default is YES when using the Concise Auxiliary File Header +format. + + This parameter is only enforced when the Create_if_not_found field +for a Legacy Auxiliary File Header is set to PROMPT. Otherwise, YES is +assumed. YES means that objects that cannot be found will be created +while reading DATA sections from "filename". + + +This command loads the auxiliary file named "ThreeBuses.aux" into the current simulation case. +By setting the CreateIfNotFound parameter to YES, any objects contained in Legacy Auxiliary File +Header DATA sections that do not already exist in the case will be created during the loading +process. +LoadAux("ThreeBuses.aux", YES); + +LoadAuxDirectory("filedirectory", "filterstring", CreateIfNotFound); +Use this action to load multiple auxiliary files from a specified directory. The auxiliary files will be loaded +in alphabetical order by name. + +"filedirectory" : The directory where the auxiliary files are located. +"filterstring" : Optional – if not specified then all files in the directory are loaded. + If specified, only files meeting this filter will be loaded.

YES means that objects which cannot be found will be + +created. If this parameter is not specified, NO is assumed. + + +This command loads data from the CSV file named "3BusCSV.csv". The YES parameter means that +if any objects referenced in the CSV file do not already exist in the case, they will be created +during the loading process. +LoadCSV("3BusCSV.csv", YES); + +LoadData("filename", DataName, CreateIfNotFound); +Use this action to load a named Data Section from another auxiliary file. This will open the auxiliary file +denoted by "filename", but will only read the data section specified. + +"filename" : The filename of the auxiliary file being loaded. +DataName : The specific data section name from the auxiliary file that should be + +loaded. +CreateIfNotFound : Optional – default is NO when using the Legacy Auxiliary File Header + +format. Default is YES when using the Concise Auxiliary File Header +format. + + This parameter is only enforced when the Create_if_not_found field +for a Legacy Auxiliary File Header is set to PROMPT. Otherwise, YES is +assumed. YES means that objects that cannot be found will be created +while reading DATA sections from "filename". + + +This command loads only the DATA section named "BusData" from the auxiliary file +"ScenarioData.aux". By setting the CreateIfNotFound parameter to YES, any objects contained in +Legacy Auxiliary File Header DATA sections that do not already exist in the case will be +automatically created during the loading process. +LoadData("ScenarioData.aux", "BusData", YES); + +LoadScript("filename", ScriptName, CreateIfNotFound); +Use this action to load a named Script Section from another auxiliary file. This will open the auxiliary file +denoted by "filename", but will only execute the script section specified. + +"filename" : The filename of the auxiliary file being loaded. +ScriptName : The specific script section name from the auxiliary file that should be + +loaded. +CreateIfNotFound : This parameter is ignored and always assumed to be NO. This does not + +mean that objects loaded from DATA sections will not be created. The +default behavior for how objects are created is followed depending on + + 24 + + + +DATA sections being specified in the Concise Auxiliary File Header or the +Legacy Auxiliary File Header format.

PowerWorld uses this to help with various pre-processing steps in the +power flow solution. This information is related to angle smoothing and generator MW estimation +features of the power flow solution. Typically, this information is a great aid in getting successful power +flow solutions, however in some circumstances you may be using an AUX file to edit information you +know is good and would not want PowerWorld to modify the initial bus voltage and angle nor the +generator MW outputs before a solution is attempted.

It will identify pockets of buses bounded by branches that meet the condition +that the absolute value of the voltage difference across the branch is greater than VoltageThreshold or +the absolute value of the angle difference across the branch is greater than AngleThreshold and the +branch meets the specified filter. + +VoltageThreshold : Per-unit voltage difference (absolute value) that determines if a branch +can be considered when determining groups of radial buses. + +AngleThreshold : Angle difference in degrees (absolute value) that determines if a branch +can be considered when determining groups of radial buses. + +filter : This is an optional parameter that is used to specify which branches are +checked.

If the absolute voltage difference across a +branch exceeds 0.1 per unit, or the angle difference exceeds 10 degrees, that branch helps define +a "pocket" of buses. The tool will then determine the buses in each pocket and estimate voltages +better using known good values outside the pocket. +ConditionVoltagePockets(0.1, 10, ALL); + +DiffCaseClearBase; +Call this action to clear the base case for the difference flows abilities of Simulator. +In Version 21 and earlier this script command was called DiffFlowClearBase.

This function would have no affect on a +traditional planning model representation, which has no breakers or disconnects explicitly defined. + +The purpose of the function is to allow the user to take a contingency set that is defined with outages of +breakers and disconnects in a full topology model and convert them to outages of the traditional +planning model elements, such as generators, loads, transmission lines, etc. This would be used in +conjunction with the ability to save a full topology model as a consolidated model. A consolidated model +reduces the full model down to a traditional planning model by examining the breaker and disconnect +statuses, and reducing the system down by consolidating breakers and disconnects that are in service. The +resulting model is a smaller model with the traditional planning elements represented, but breakers and +disconnects have been removed and nodes aggregated into bus representations. This function will also +take the breaker and disconnect statuses and convert contingencies defined with the breakers and +disconnects and convert them into contingencies of the planning model devices affected by opening the +original breakers and disconnects. Thus you could create a contingency set that is defined for the +consolidated model, and can be run on the consolidated model with the same results as if the original +contingency set is run on the full topology model. + +The parameter KeepOriginalIfEmpty is a YES or NO option to retain or not the original contingency +definitions for any contingencies that do not end up isolating any devices.

These Model Expressions must be specified by name as the +key field for identifying them within the power flow case. There must be +as many Model Expressions defined as there are columns of MatrixM and +MatrixA (m). + +MatrixM : This is an nxm matrix of floating point values.

It is possible that there will be no limit in either +the minimum or maximum direction and -INF or INF can be used to +indicate this instead of a floating point value. + +VectorL : This is an nx1 vector of floating point values. This vector must be the +same size as the number of rows in MatrixM. + +MatrixA : This is an nxm matrix of floating point values. This matrix must be the +same size as MatrixM. This matrix is optional and does not have to exist +in the input file. If not specified, it will be assumed that all entries are 0 +and it is the same size as MatrixM. Previous versions of the script +command named this MatrixL1.

Older versions of Simulator +only support the Legacy Auxiliary File Header below. All versions of Simulator support reading the legacy header format. +When writing out an auxiliary file there is an option starting in Simulator Version 19 called Use Concise Variable Names +and Auxiliary File Headers that determines whether to write out the DATA keyword and other arguments or to write out +the concise auxiliary file header. See the online help documentation for more details: +http://www.powerworld.com/WebHelp/#MainDocumentation_HTML/Auxiliary_Files.htm + +When using the concise format, the data between the curly braces is always written using space delimiter and +Create_if_not_found is always assumed to be YES. + +Legacy Auxiliary File Header +DATA DataName(object_type, [list_of_fields], file_type_specifier, create_if_not_found) +{ +data_list_1 + . + . + . +data_list_n +} + +Immediately following the DATA keyword, you may optionally include a DataName. By including the DataName, you can +make use of the script command LoadData("filename", DataName) to call this particular data section from another +auxiliary file. Following the optional DataName is an argument list. The argument list is contained inside left and right +parentheses "( )". There are 4 arguments in this list which will be described shortly: object_type, [list_of_fields], +file_type_specifier, and create_if_not_found. + +ObjectType +The object_type parameter identifies the type of object or data element the information section describes or models. +For example, if object_type equals BUS, then the data describes BUS objects. + +There are some special object types that start with the keyword REMOVED. If these are loaded into Simulator while in Edit +mode, the corresponding objects will be deleted. For example REMOVEDBUS will delete BUS objects, REMOVEDBRANCH +will delete BRANCH objects, etc. Not all object types have a corresponding REMOVED object type, and simply prepending +this keyword to the front of an object_type will not allow this functionality. The objects that exist of this with this +functionality are the ones that allow comparison of topological changes through the Difference Flows tool. + +The list of object types Simulator’s auxiliary file parser can recognize will grow as new applications are developed. Within +Simulator, you will always be able to obtain a list of the available object types by going to the main menu and choosing +Window, Export Case Object Fields, and then exporting the objects to Excel or a text file. + + 154 + + + +File_Type_Specifier +When using the Legacy Auxiliary File Header, the file_type_specifier parameter distinguishes the information +section as containing custom auxiliary data (as opposed to Simulator’s native auxiliary formats), and indicates the format +of the data. The parser recognizes two values for file_type_specifier: + +(blank) or AUXDEF or DEF Data fields are space delimited +AUXCSV or CSV or CSVAUX Data fields are comma + +delimited + +Required Fields and Create_if_not_found +Each ObjectType in PowerWorld has a set of Required Fields that must be included in the List_of_Fields when using an +Auxiliary File to create a new object. These Required Fields are highlighted in green in the user interface. If these Required +Fields are not included in the List_of_Fields, then new objects will never be created, and the Auxiliary file will only edit +existing objects. When using the Concise Auxiliary File Header, if the required fields are given, then new objects will be +created. There are also some restrictions for objects that define the network topology and these objects may only be +created while in Edit Mode: Bus, Gen, Load, Shunt, Branch, LineShunt, DCTransmissionLine, VSCDCLine, MSLine, +3WXFormer, MTDCRecord, MTDCBus, MTDCLine, and MTDCConverter. + +In addition to specifying these fields, when using the Legacy Auxiliary File Header, an optional field +Create_if_not_found must be specified. In the Legacy header, objects will only be created if all Required Fields are +given and the Create_if_not_found=YES. If the value is NO, objects will not be created. If Create_if_not_found +is omitted in the Legacy header, YES is assumed. If loading an auxiliary file using the LoadAux script command, the +Create_if_not_found field for the data section will override the Create_if_not_found field with the script. Only if +the Create_if_not_found field for the data section is set to PROMPT will the field for the script command be used. +To repeat, regardless of the choice of CreateIfNotFound, a new object will only be created if a particular list of +Required Fields is in the List_of_Fields. + +List_of_Fields +The list_of_fields parameter lists the types of values the ensuing records in the data section contain. The order in +which the fields are listed in list_of_fields dictates the order in which the fields will be read from the file. Simulator +currently recognizes many different field types, each identified by a specific field variable name. Because the available +fields for an object may grow as new applications are developed for the convenience of our customers, you will always be +able to obtain a list of the available object types and fields by going to the main menu and choosing Window, Export +Object Fields, and then choosing to export to Excel or a text file. Certainly, only a subset of these fields would be found in +a typical custom auxiliary file. In crafting applications to export custom auxiliary files, developers need concern themselves +only with the fields they need to communicate between their applications and Simulator. A few points of interest +regarding the list_of_fields are: + +• The list_of_fields may take up several lines of the text file. +• When using the older heading starting with the keyword DATA, the list_of_fields should be enclosed by + +square brackets [ ]. When using the concise heading these square brackets are not used. +• When encountering the PowerWorld comment string ‘//’ in one of these lines of the text file, all text to the right is + +ignored. +• Blank lines, or lines whose first characters are ‘//’ will be ignored as comments. +• Field variable names must be separated by commas. + +Example: the following are equivalent representations + DATA (BUS, [NomKV, Number, // comment here BUS (NomKV, Number, // comment here + + VAngleA, VAngleB, VpuA, VpuB, VAngleA, VAngleB, VpuA, VpuB, + // comments allowed here too // comments allowed here too + + // note that blank rows are ignored // note that blank rows are ignored + AreaNum, VAngle, ActB, Equiv, ActG, AreaNum, VAngle, ActB, Equiv, ActG, + kV, MargCostMW, LoadMVA, // more comment kV, MargCostMW, LoadMVA, // more comment + LoadMW, LongName]) LoadMW, LongName) + + 155 + + + +Concise Field Variable Names +Variable names within Simulator were overhauled starting with Version 19. Most no longer utilize the special location +integer and instead spell out such information in the field variable name. In general, the variable names have been made +more concise or at least more understandable. Therefore what was once called for a BRANCH object LineMW:1 is now +called MWTo. Similarly LineMW:2 is now called MWFromCalc (representing the MW flow at the from bus of branch +calculated from the terminal voltages). The only fields that continue to use the location integer are those that represent +fields for which a dynamic number of fields are available. Examples of this include the CustomInteger, CustomString, and +CustomFloat fields which use the location integer to specify which value is used. Other examples include the multiple +direction PTDF results fields PTDFMult:0, PTDFMult:1, and so on. + +When writing out an auxiliary file there is an option within Simulator Version 19 called Use Concise Variable Names and +Auxiliary File Headers that determines whether to write out the DATA keyword and other arguments or to write out the +concise auxiliary file header. See the online help documentation for more details: +http://www.powerworld.com/WebHelp/#MainDocumentation_HTML/Auxiliary_Files.htm + +Legacy Field Variable Naming +When listing fields, some field variable names may be augmented with a field location. These are in the format +variablename:location. One example of this is the field LineMW. For a branch, there are two MW flows associated +with the line: one MW flow at the from bus, and one MW flow at the to bus. So that the number of fields does not +become huge, the same field variable name is used for both of these values. For the from bus flow, we write LineMW:0, +and for the to bus flow, we write LineMW:1. Note that field variable names using a location of 0, such as LineMW:0, may +simply leave off the :0. + +These field variable names have been updated with Concise Field Variable Names starting in Simulator version 19. These +are described in the next section. The Legacy field variable names can still be used to support existing auxiliary files or +files needed for loading into earlier versions of Simulator. + +Special Naming +There are several fields that can be referred to by the user-defined name for the field rather than using the location +number. These are fields that might have their location numbers change when different auxiliary files are merged in the +same case. Referring to these by name can eliminate this possible confusion. These fields can be defined in the format +variablename:location_by_name. They can also be referred to by location number as well. + +Fields that allow referring to the location by name are: + +• Expressions – "CustomExpression:my expression name" +• String Expressions – "CustomExpressionStr:my string expression name" +• Custom fields (Floating Point, Integer, and String) – "CustomSingle:my custom single name". Using this + +format for custom fields requires that Custom Field Descriptions be created for the fields to be used. +• Calculated Fields – "BGCalcField:my calculated field variable name" + +Key Fields +Simulator uses certain fields to identify the specific object being described. These fields are called key fields. For example, +the key field for BUS objects is BusNum, because a bus can be identified uniquely by its number. The key fields for GEN +objects are BusNum and GenID. To properly identify each object, the object’s key fields must be present. They can +appear in any order in the list_of_fields (i.e. they need not be the first fields listed in list_of_fields). As long as the +key fields are present, Simulator can identify the specific object. By going to the main menu and choosing Window and +then Export Case Object Fields you will obtain a list of fields available for each object type in either Excel or text format. In +this output, the key fields will appear with asterisks *. + + 156 + + + +Data List +After the data argument list is completed, the Data list is given. The data section lists the values of the fields for each +object in the order specified in list_of_fields. The data section begins with a left curly brace and ends with the a +right curly brace. A few points of interest regarding the value_list: + +• The value_list may take up several lines of the text file. +• Each new data object must start on its own line of text. +• When encountering the PowerWorld comment string ‘//’ in one of these lines of the text file, all text to the right + +of this is ignored. +• Blank lines, or lines whose first characters are ‘//’ will be ignored as comments. +• Remember that the right curly brace must appear on its own line at the end of the data_list. +• If the file_type_specifier is CSV, the values should be separated by commas. Otherwise, separate the field + +variable names using spaces. +• Strings can be enclosed in double quotes, but this is not required. You should however always inclose strings that + +contain spaces (or commas) in quotes. Otherwise, strings containing commas would cause errors for comma- +delimited files, and spaces would cause errors for space-delimited formatted files. + +Special Data List Entries +When specifying values in case information displays, AUX files, and script commands, there are some special formats that +can be used. These formats will allow the value of a model or object field to be used instead of specifying an explicit +value. Formats that are allowed include those described in the Special Identifiers for Model Fields in Data section as +well as others mentioned below in this section. + +A string of the format "@Variablenamelegacy:location:digits:decimals" +Or "@concisename:location:digits:decimals" +will be treated as though the value of the named variable is entered in the field, with digits total and decimals digits +to the right of the decimal point. This format may be used in case information displays, AUX files, and script commands +that set values. String fields that can be converted to a valid numeric value can be used to populate either floating point +or integer fields. Floating point values that are used to populate integer fields are truncated before populating the integer +field. + +When parsing an AUX file while reading, the treatment of concise and legacy variable names is automatically handled by +the parser. + +There are specific fields for specific object types that allow referencing a model field definition as the value of the field. +The model field definition is specified in this syntax: @MODELFIELD. +The model field definition and not the value of the model field itself is used as the value of the field until the field is used +for its intended purpose. The fields that can be specified in this manner include those that specify directory paths and file +locations. When an action is carried out that requires using the directory path or file location, the model field definition is +converted to the value that it represents and that gets used as the location of the file or directory path. + +The following object types and fields (given by variable name) can use this special model field syntax: Transient_Options +(RSHD_Directory), PVCurve_Options (PVCOutFile, PVCStoreStatesWhere), QVCurve_Options (QVOutputDir, +QVOutputFileName), CTG_Options (PostCTGSolAuxFile, PostCTGAuxFile, HardDriveFileName), Sim_Environment_Options +(SEOSpecifiedAuxFile:0, SEOSpecifiedAuxFile:1, SEOSpecifiedAuxFile:2) and MessLog_Options (LogAutoFileName). + +Special Identifiers for Model Fields in Data +The following special formats can be used in case information displays, AUX files, and script commands that set values. +They are also used in some script commands as part of parameters that input text. These formats will allow the value of a +model or object field to be used instead of specifying an explicit value. + + + 157 + + + +A string in the format "&ModelExpressionName:digits:decimals" will be treated as though the value of the +named model expression is entered in the field, with digits total and decimals digits to the right of the decimal point. +If no digits or decimals are specified, 7 decimal places will be used. Trailing zeros will be removed if no decimals are +specified. + +A string of the format "&Objecttype 'key fields' variablenamelegacy:location:digits:decimals" +Or "&Objecttype 'key fields' concisename:digits:decimals" +will be treated as though the value of the named object and object field is entered in the field, with digits total and +decimals digits to the right of the decimal point. If no digits or decimals are specified, 7 decimal places will be used. +Trailing zeros will be removed if no decimals are specified. +This syntax can be used when specifying the values of key fields used for identifying objects when using SetData and +CreateData script commands. + +Example: +Use a SetData command to open a branch that has the highest loading in the case. +Create a calculated field that returns the maximum loading for a branch object and +then apply this to the PWCaseInformationObject. Use the ObjectID for the branch +identification and the CalcFieldExtra field to return the string identifier for the +object that meets the calculated field conditions. + +SetData(Branch, [ObjectID, Status], ["&PWCaseInformation +'CalcFieldExtra:HighestLoading'", "Open"]); + + + +A string of the format "&Objecttype '@variablenamelegacy:location' +variablenamelegacy2:location:digits:decimals" +Or "&Objecttype '@concisename' concisename2:digits:decimals" +will use a specific field for one object, variablenamelegacy or concisename, to determine the key field value for the +objecttype object. This will be treated as though the value of the named object and object field, variablename2 or +concisename2, is entered in the field, with digits total and decimals digits to the right of the decimal point. If no +digits or decimals are specified, 7 decimal places will be used. Trailing zeros will be removed if no decimals are specified. + +Example: +Set the CustomFloat field for every load to the MW value of that load’s zone. + +SetData(Load, [CustomFloat], ["&Zone '@ZoneNumber' LoadMW"], All); + + +(Added in the August 1, 2023 patch for Simulator 23) +A string of the format "&@variablenamelegacy variablenamelegacy2:location:digits:decimals" +Or "&@concisename concisename2:digits:decimals" +will use a specific field for one object, variablenamelegacy or concisename, to determine the objecttype and key +field for identifying another object. This will be treated as though the value of the named object and object field, +variablename2 or concisename2, is entered in the field, with digits total and decimals digits to the right of the +decimal point. If no digits or decimals are specified, 7 decimal places will be used. Trailing zeros will be removed if no +decimals are specified. + +Example: +Set the CustomFloat field for every load to the MW value of the zone identified by the +objecttype and key field identifiers contained in the CustomString field for each +load. + +SetData(Load, [CustomFloat], ["&@CustomString LoadMW"], All); + + + + + + 158 + + + +Using Labels for Identification +Most data objects (such as buses, generators, loads, switched shunts, transmission lines, areas, zones, and interfaces) may +have an alternative names assigned to them. These alternative names are called labels. Labels allow you to refer to +equipment in the model in a way that may be unique to your organization. Labels may thus help clarify which elements +are described by a particular set of data, especially when the short names employed by the power system model prove +cryptic. Furthermore, since labels are likely to change less frequently than bus numbers, and since a label must, by +definition, identify only one power system component, they may function as an immutable key for importing data from +auxiliary files into different cases, even when bus numbering schemes change between the cases. Labels must be unique +for devices of the same type, but the same label can be used for a device of a different type. + +Information dialogs corresponding to buses, generators, loads, switched shunts, transmission lines, areas, zones, and +interfaces feature a button called Labels. If you press this button, the device’s Label Manager Dialog will appear. The Label +Manager Dialog lists the labels associated with the device. You can delete a label from the list by selecting it and pressing +the delete key on the keyboard or clicking the Delete button. You may add a label to the device by typing its name in the +textbox and pressing the Add New button. You will not be allowed to add a Label that already exists for the same type of +device. A single power system device may have multiple labels, but each label may be associated with only one device of a +given type. For example, a bus could have the label Bus North while a generator could also have the same label, but there +could not be another bus or generator with this same label. + +You also may designate a particular label to be the primary label for the device by checking the box Primary before adding +the label. Alternatively, you can select the device from the list and click the Make Primary button. A device’s primary label +is the one that is listed first in the Labels (All) field (variablename = LabelsAll) in a Case Information Display. This +field lists all labels assigned to a device as a comma-delimited string. Any label can be used to import data from auxiliary +data files. + +Labels can be used to map data from an auxiliary data file to a power system device. Recall that auxiliary data files require +you to include a device’s key fields in each data record so that data may be mapped to the device. Labels provide an +alternative key. Instead of supplying the bus number to identify a bus, for example, you can supply one of the bus’s labels. +The label will enable Simulator to associate the data with the device associated with that label. This mechanism performs +most efficiently when the primary label is used, but other labels will also provide the mapping mechanism. The Label (for +use in input from AUX or Paste) field (variablename = Label) is used for importing data using labels and is blank +when viewing in a case information display. Keep in mind that all devices read via an auxiliary file using the label field +should have a non-blank label. Otherwise, information for that device will not be read. Even if the primary or secondary +key fields are provided with the device, as long as the label field is present, that is the only field that will be used to +identify the device. New devices cannot be created by simply identifying them by label. Either the primary or secondary +key fields must be present to create a new device and the label field should not be present. +Again, it is important to remember this: a single power system device may have multiple labels, but each label may be +associated with only one device of a particular type. This is the key to enabling data to be imported from an auxiliary file +using labels. + +Saving Auxiliary Files Using Labels +All devices that can be identified by labels will have the Labels (All) and Label (for use in input from AUX or Paste) fields +available in their case information displays. In order to save auxiliary files that identify devices by label, the two label fields +should be added to the case information display prior to saving the data in an auxiliary file. Because the Label (for use in +input from AUX or Paste) field will be blank when saved in the auxiliary file, this field must be populated with one of the +labels in the Labels (All) field before loading the auxiliary file back in. Keep in mind that devices with blank labels cannot +be identified when loading in an auxiliary file, so avoid saving auxiliary files by label if all devices do not have labels. Note +that when saving out an entire case as an auxiliary file, the field "AllLabels" is included for each object type that allows +labels and has some labels defined. + +Many devices require SUBDATA sections. These sections have custom formats specific to the type of information that they +contain. When saving auxiliary files with devices that require SUBDATA sections, the user can choose to use primary or + 159 + + + +secondary key fields or labels to identify devices in the SUBDATA sections. The user will either be prompted when saving +the devices, or there is an option to change the key field to use when saving subdata sections on the PowerWorld +Simulator Options dialog under the Case Information Displays category. When choosing to use labels, if a device has a +label, it will be used. If it is a device that can be identified by buses and bus labels exist, bus labels will be used. Finally, if +the device does not have a label and the buses do not have labels, the primary key for the device will be used for +identification. + +Devices that have SUBDATA sections that contain other devices that can be identified by labels include: contingencies, +interfaces, injection groups, post power flow solution actions, and owners. + +The setting to choose which identifier to use for the SUBDATA sections does not just apply to SUBDATA sections. Often +when saving groups of options, this setting will apply to everything being saved with those options and not just the +SUBDATA sections. This includes contingency options, ATC options, limit monitoring settings, and PVQV options. In these +cases, there will be a prompt asking the user to decide which identifier to use in the auxiliary file. + +Loading Auxiliary Files SUBDATA Sections Using Labels +The various SUBDATA sections that represent references to other objects can also be read using labels. Examples include +contingencies, interfaces, injection groups, post power flow solution actions, and owners. When reading a +SUBDATA section such as this, PowerWorld makes no assumption ahead of time about what identification was used to +write this SUBDATA section. Instead, an order of precedence for the identification is as follows + + + Identification Explanation Example +1 Key Fields assumes that the strings represent Key Fields BRANCH 8 9 1 +2 Secondary assumes that the strings represent Secondary BRANCH Eight_138 Nine_230 1 + +Key Fields Key Fields +3 Labels for the key/secondary key fields for some objects BRANCH Label8 Label9 1 + +component consist of references to other objects. An +objects example of this is the BRANCH object that is + +described by the From Bus, To Bus, and +Circuit ID. This assumes that labels of the +component objects are used. + +4 Labels Assumes that the string represents one of the BRANCH LabelForBranch +Labels of the object + +Special Use of Labels in SUBDATA +There are a few special cases where objects have fields that identify other devices. These devices can be identified by label +but not in the conventional means because the label field applies to the object that contains the device and a SUBDATA +section is not necessary. These special cases include: (Note all fields given below are by variable name because the use of +labels is most relevant with auxiliary files.) + +ATC Scenarios +ATC Scenario change records usually contain primary key fields to identify the devices that should be +adjusted during the scenario. If using labels, these primary key fields will be replaced with a single Label +field. The use of this field is different because the Label field refers to the device in the change record and +not to the change record itself. When labels are used with ATC scenarios, device labels only can be used. +Bus labels cannot be used to identify devices for which no label exists but a bus label does. + +ATC Extra Monitors +ATC Extra Monitors identify either branches or interfaces to monitor during the ATC analysis. These +devices are identified in the WhoAmI field of ATC Extra Monitor records. Usually, the WhoAmI field is a +special format that contains key field tags. Optionally, this field can use the label of the device for the + + 160 + + + +extra monitor. If the device label is not available, the standard format will be used. There is no option to +use bus labels if they exist and the device labels do not. + +Model Conditions +Devices in Model Conditions are usually identified by the WhoAmI field which is in a special format that +contains key field tags. Optionally, this field can use the label of the device. If the device label does not +exist, the standard format will be used. There is no option to use bus labels if they exist and the device +labels do not. + +Model Expressions +Model Expressions contain Model Fields. Model Fields are identified by the WhoAmI fields in the Model +Expressions. Usually, the WhoAmI fields are in a special format that contains key field tags. Optionally, +these fields can use the label of the device associated with the Model Field. If the device does not exist, +the standard format will be used. There is no option to use bus labels if they exist and the device labels do +not. + +Bus Load Throw Over Records +Bus Load Throw Over Records are used with contingency analysis. These records have an option to +identify the bus to which the load will be transferred by either number or name_kV combination. If +choosing to identify objects by label, the BusName_NomVolt:1 field will contain the label of the bus +instead of the name_kV combination. Bus Load Throw Over Records will be saved in an auxiliary file if +choosing to Save settings on the Contingency Analysis dialog. + +Injection Group Participation Points +All participation points and the injection groups to which they belong can be listed on the Injection Group +Display. Load, generator, bus, and shunt devices that can be assigned to a participation point must be +identified by bus and ID. The bus can be identified by either the number or name. When identifying by +name, the BusName_NomVolt field is used to provide the name_kV combination for the bus. If choosing +to identify devices by label, this field instead will contain the label of the device. If the device does not +have a label but the bus does, the bus label will be used instead in conjunction with the ID of the device. +Even if the device does contain a label, the ID field must be included in any auxiliary file that is going to +be loaded because it is a key field. Injection groups can be included in other injection groups. Injection +groups can be identified by label, even though this is not a normal thing to do. If any injection groups +have labels and these injection groups are included in other injection groups, their labels will also appear +in the BusName_NomVolt field. If they do not have labels, they will be identified by the injection group +name that appears in the PPntID field. + + 161 + + + +SubData Sections +The format described thus far works well for most kinds of data in Simulator. It does not work as well however for data +that stores a list of objects. For example, a contingency stores some information about itself (such as its name), and then a +list of contingency elements, and possible a list of limit violations as well. For data such as this, Simulator allows +, tags that store lists of information about a particular object. This formatting looks like the +following + + +object_type (list_of_fields) +{ +value_list_1 + + precise format describing an object_type1 + precise format describing an object_type1 + . + . + . + + + precise format describing an object_type2 + precise format describing an object_type2 + . + . + . + +value_list_2 + . + . + . +value_list_n +} + + +Note that the information contained inside the , tags may not be flexibly defined. It must be +written in a precisely defined order that will be documented for each SubData type. The description of each of these +SubData formats follows. + + 162 + + + +ATC_Options +RLScenarioName +GScenarioName +IScenarioName + +These three sections contain the pretty names of the RL Scenarios, G Scenarios, and I Scenarios.

An optional fourth field may be included if we are using one of the iterated +ATC solution options. This field must be the String "ATCFlowValue". + +Monitor Description : Contains a string describing which monitor this belongs to. +InitialValue : Contains the value for this extra monitor at the last linear iteration. +Sensitivity : Contains the senstivity of this monitor. +ATCFlowValue : A string which signifies that a block will follow which stores a list of flow + +values for specified transfer levels.

These three values are written on a single line of text. Each line contains +two values: + +cmvalue : Real number between 0 and 100 (minimum to maximum value). +cmcolor : Integer between 0 and 16,777,216. Value is determined by taking the + +red, green and blue components of the color and assigning them a value +between 0 and 255. The color is then equal to red + 256*green + +256*256*blue. + +cmalpha : Integer between 0 and 255, where only 0 and 255 are valid values. A +value of 0 indicates that the color point is transparent, while a value of +255 indicates that the color point is opaque.

See the DATA Section and its sub-sections for +details on the proper syntax. Any differences for display auxiliary files will be discussed below. + +Key Fields +See the Key Fields topic in the DATA Section for general details. + +Display objects have an additional key field used for identification because multiple objects can be present on the same +one-line diagram that represent the same power system element. This extra key field is SOAuxiliaryID. This is a field +that is unique for each type of display object and other key field combination. If there are two display buses that +represent bus one in the power system, the SOAuxiliaryID field will be different for both. Simulator will automatically +create unique identifiers when these objects are created graphically. They can also be user specified but are forced to be +unique. This field does not need to be present when reading in a display auxiliary file, but if it is missing, Simulator +assumes that the ID is "1". This field is the only key field identifier for objects that do not link to power system elements +such as background lines and pictures, and therefore, should always be included when reading in these objects or the +expected results may not be achieved. + +By going to the main menu and choosing Help, Export Display Object Fields you will obtain a list of fields available for +each display object type. In this output, the key fields will appear with asterisks *. + +Special Data Sections +There are several object types that should be noted here because they can impact the reading of an entire display auxiliary +file, overall look of the resulting one-line diagram, or require special input to properly import/export the object. + +GeographyDisplayOptions +Most objects supported in the display auxiliary file have coordinates that can be specified in the appropriate data sections. +What these coordinates specify can be controlled by the GEOGRAPHYDISPLAYOPTIONS object. This object has only two +fields available: MapProjection and ShowLonLat. There are four possible settings for MapProjection: "x,y", "Simple +Conic", "Alaska", and "Mercator". The choice of projection will determine how the x,y values for display objects are +interpreted. ShowLonLat can be either "YES" or "NO". If ShowLonLat is "YES", the setting specified for the +MapProjection will be the longitude,latitude projection used when reading/writing the object x,y values. If ShowLonLat is +"NO", the x,y values will always be interpreted as x,y regardless of the MapProjection setting. This object should be placed +in the display auxiliary file before any other objects containing coordinates are read. If this object is not included in the +auxiliary file, the coordinates will be interpreted based on the current settings of map projection and whether or not +coordinates are showing longitude,latitude. + +Picture +PICTURE objects represent background images that cannot be stored in a text file format. To properly include a PICTURE +object in a display auxiliary file, the file containing the image must be saved and read along with the auxiliary file. The +FileName field indicates the name and location of the image file. If the image file cannot be found when reading in a +display auxiliary file and attempting to create a new object, no PICTURE object will be created. If attempting to update an +existing object and the image file cannot be found, the object will not be updated with a new image, but the FileName +field will be updated with the specified file name. + +PWFormOptions +One-line display options that affect the current display settings can be changed by using the PWFORMOPTIONS object. +Usually, this object specifies named sets of options that can be selected and used to change the various one-line display +options through the GUI. By including a specially named object, the current options can be changed through a display +auxiliary file. PWFORMOPTIONS are named using the OOName field. Setting this field to + + 214 + + + +"THESE_OPTIONS_ARE_APPLIED_TO_THE_CURRENT_DISPLAY" will apply the specified set of options to the current one-line +when the file is read. When saving the entire one-line to a display auxiliary file, a PWFORMOPTIONS object with this name +is added to the file by default. + +View +Different views can be specified in the display auxiliary file using the VIEW object. Usually, this object is used to specify +named sets of options used to select and change the view through the GUI. By including a specially named object, the +current view can be changed through a display auxiliary file. VIEW objects are named using the ViewName field. Setting +this field to "THIS_VIEW_IS_APPLIED_TO_THE_CURRENT_DISPLAY" will apply the specified set of view options to the current +one-line when the file is read. When saving the entire one-line to a display auxiliary file, a VIEW object with this name is +added to the file by default. + +SubData Sections +The format described thus far works well for most kinds of data in Simulator. It does not work as well however for data +that stores a list of objects. For example, a contingency stores some information about itself (such as its name), and then a +list of contingency elements, and possible a list of limit violations as well. For data such as this, Simulator allows +, tags that store lists of information about a particular object. This formatting looks like the +following + + +object_type (list_of_fields) +{ +value_list_1 + + precise format describing an object_type1 + precise format describing an object_type1 + . + . + . + + + precise format describing an object_type2 + precise format describing an object_type2 + . + . + . + +value_list_2 + . + . + . +value_list_n +} + + +Note that the information contained inside the , tags may not be flexibly defined. It must be +written in a precisely defined order that will be documented for each SubData type.

Each set of coordinates can +be enclosed in square brackets, [ ], or the brackets can be eliminated. The brackets will be included when +Simulator generates an auxiliary file. The individual coordinates are separated by the specified delimiter, +either a space or a comma, and if the brackets are included, the same delimiter should be used to +separate sets of coordinates. The list of points is in a somewhat free form and sets of coordinates can +span multiple lines. Each point should either be in x,y coordinates or longitude,latitude coordinates. +Which coordinates should be used depends on the current option settings for map projection and +whether or not coordinates should be shown in longitude,latitude. If the display auxiliary file is +automatically generated by Simulator, a comment will be included in the subdata section indicating the +coordinate system in use during file creation. + +Example using brackets and a comma delimiter: + +//Coordinates are x,y + [14.00000000, 63.00000000], [14.00000000, 60.00000000], + [20.00000000, 45.00000000], [20.00000000, 42.00000000] + + +Example with no brackets and a space delimiter: + +//Coordinates are x,y + 14.00000000 63.00000000 14.00000000 60.00000000 + 20.00000000 45.00000000 20.00000000 42.00000000 + + +DynamicFormatting +Same format as in data auxiliary files. + +Filter +Same format as in data auxiliary files. + +GeoDataViewStyle +Same format as in data auxiliary files. + + 216 + + + +PieChartGaugeStyle +ColorMap + +This is a lookup table by percentage of scalar and color values.
