Hi Francisco,
The "Combine Cases" method described in
sam.nrel.gov/forum/forum-general/3001 simply adds the electricity output of the PV and CSP system together to calculate the system's total output.
UPDATE: As of SAM 2021.12.02, the Combine Cases macro is replaced by the Calculate generation profiles and nameplate capacity from open cases option on the Power Plant page for the Generic System model and Generic Battery model. See the SAM YouTube channel for a
short tutorial
.
There is not a way to operate the CSP system in response to the output of the PV system. You would have to do that outside of SAM. You could use SAM to determine the hourly generation profile over one year of both systems, and then try to make adjustments to the CSP output, but I do not have a suggestion of how exactly to do that.
PySAM does not give you access to the internal calculations of the model, so I'm not sure that would solve the problem. It does allow you to set values of inputs, run simulations, and make calculations on output variables.
Best regards,
Paul.
