Development of photovoltaic simulator based on DC-DC converter

This paper introduces the photovoltaic (PV) simulator for the inverter of PV energy system. In order to embody the PV simulator, the conventional solar cell is numerically modeled based on the one-diode equivalent circuit. With the P-V relationships, we find the maximum and minimum power which is needed during the inverter performs the MPPT algorithm and design the parameter based on the maximum and minimum power. Finally, this paper verifies design parameters numerically through the PSIM and analyzes the PV simulator in the frequency domain using matlab.
