Hi Waleed,
Are you planning to build your model in Python using the NREL PySAM package (
nrel-pysam.readthedocs.io/en/main/), or are you trying to build a model in C++ using modules from the SSC repository (
github.com/NREL/ssc/)?
The Electricy Thermal Energy Storage model was developed to work with other modules for system control, heater, power cycle, etc. that are managed by the SAM desktop application. It is tricky to get it to work as a standalone module.
Please let me know more about what you are trying to do and I will see if I can point you in the right direction.
Best regards,
Paul.
