A PV generation system based on P&O MPPT algorithm and SVPWM inverter for standalone applications

Abstract

The output of photovoltaic cells continues to change with surrounding environments, therefore, the maximum power point of the solar cell relies on the amount of solar irradiation and environment temperature. Maximum Power Point Tracking (MPPT) technology is utilized in photovoltaic systems to take entire advantage of output power for Photovoltaic cells. Power Inverters also is an important side of Photovoltaic power generation. This paper proposed a Perturb and Observe (P & O) MPPT algorithm with space vector pulse width modulation (SVPWM) control method for a three-phase complete stand-alone Photovoltaic generation system. The proposed PV generation system is implemented into Matlab / Simulink. Simulation results show the proposed stand-alone Photovoltaic system can achieve the excellent execution of MPPT and get the output voltage in high quality. The system is tested and verified using a solar cell Kyocera Solar KD215GX-LPU PV module.

A Novel MPPT Technique Based on Combination between the Incremental Conductance and Hysteresis Control Applied in a Standalone PV System

“…Different algorithms have been developed and implemented by researchers in this context. Among these algorithms, we note Perturb and Observe (P&O) [6,7]. Its principle consists in disturbing the voltage of the PV array and comparing the instantaneous power with that of the previous disturbance.…”
