hopp simulation results

[Hanrong-Huang]

Hi,

I wonder what does the "hybrid" represent in the results part of hopp.system.annual_energies.
For example, {"pv": 21443415.038181894, "wind": 25001454.604371652, "hybrid": 42403277.384125635}.
The “hybrid” seems does not match with PV + wind total annual energy.
And if I calculate the annual grid generation by (np.sum(hopp.system.grid.generation_profile))/25, the output is 42403277.384125635, which equals to "hybrid".
I'm a bit confused of what does hybrid represent in here.

Your response is much appreciated, thank you.
