Hi,
I am trying to model a hybrid plant of Solar Tower CSP and PV. I created a General System to combine the two cases, but after I run the simulation it gives me an error and a message regarding the CSP. You can find both the message and the final error attached.
Thank you
Luisa

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 .

Please see sam.nrel.gov/forum/forum-general/2973-hybrid-csp-pv-error-in-running-combine-cases-macros.html.

Best regards,
Paul.

Hi Luisa,

Thank you for sending the file.

In SAM 2020.2.29, the Detailed PV model runs a simulation over the analysis period to better model module degradation. It turns out that the Combine Cases macro was written to work only for simulations over a single year, which was the behavior in earlier versions of SAM. We will need to update the macro to fix the problem, which we will do for the next software update.

In the meantime, I posted instructions for a workaround on the SAM GitHub repository:

Best regards,
Paul.
