Modeling and Simulation of Photovoltaic Systems based on Three Port Inverter Topology

The modeling of PV (photovoltaic) systems is very crucial for embedded power system applications and maximum power point tracking. This paper offers a PV array and simulation of that step by step using MATLAB/Simulink software. For PV under study, P&O control method for maximum power point tracking (MPPT) under varying irradiation and temperature conditions based on new proposed three port inverter topology. The PV model has been developed and used as Simulink subsystems where the effect of solar insolation and PV array temperature on commercial PV modules have been studied throughout the simulated I-V and P-V output characteristics. The proposed model expedites simulating the dynamic performance of PV-based power systems.
