An ATP Model for Photovoltaic Module Considering the Temperature Dependence
Abstract— ATP (Alternative Transients Program) is a widely used simulation program for the electric power network. It provides the Shockley diode component that allows the user to quickly build a photovoltaic (PV) module model that can be used for simulation of an electric grid containing solar power generators. However, the diode parameters are inputted through a dialog window and cannot be varied during the simulation, which limits the program's performance of simulating cases where the PV module temperature undergoes variations. This paper proposes a method to solve this shortcoming by inserting a temperature-compensated current source in the existing equivalent circuit of PV module. Results obtained by the proposed model and by the analytical calculation are compared for validation.
Index Terms— ATP, compensation, photovoltaic, shockley diode, temperature.
