The types of data useful for model validation of solar PV plants can be divided into two categories. The first corresponds to the system’s response to repeatable tests, and the second corresponds to the system’s response to spontaneously occurring disturbances.
The turbine type of the solar PV generator is set to 31, 32, or 33.6 The turbine type of the battery generator is set to 42. The reactive capability requirement applies to the total solar PV and battery storage generators. The solar PV and battery storage each may not be able to meet the requirement alone.
SAM calculates the performance of a photovoltaic array by determining the monthly and annual insolation incident on the plane of the array (Section 6) .
