Modeling of a detailed photovoltaic generation system for EMT-type simulation

This article presents a detailed three-phase grid connected PV model which includes important control systems required for EMT-type simulation. A one diode model for the PV array is used to simulate environmental constraints such as solar irradiation. A detailed control system including dc voltage control, inner current control, MPPT and PWM control are implemented in order to simulate the model during steady state and dynamic conditions. The PV model is merged with a simple distribution network to investigate the PV's interaction with the AC grid. Several simulation scenarios are presented in order to validate the performance of the model.
