Hi Bertie,
As you know, SAM is not designed to model hybrid power systems, and it assumes that the grid is always available to either absorb excess electricity or deliver electricity when the power system cannot meet the load.
To approximate the performance of hybrid power system, you might try creating a generation profile by combining the electrical output of each of the PV systems you modeled, and using that profile as input to the Generic Battery model.
One way to calculate the combined output of the PV systems would be to use the Combine Systems macro (click
Macros under the Simulate button). You can follow the macro instructions to create the "combined" generation profile for a Generic System case as described, but then export the generation profile from the Power Plant page of the Generic System case to a text file, and then import it to a different Generic Battery case.
Another approach would be to write an
LK script
that creates the combined generation profile.
Best regards,
Paul.
