MAXIMUM POWER-POINT TRACKING OF A PHOTOVOLTAIC SYSTEM USING HYBRID COMBINATION OF GA-PSO ALGORITHM AND PID CONTROLLER

Abstract

Maximum power point tracking (MPPT) techniques are considered a crucial part in photovoltaic system design to maximise the output power of a photovoltaic array. PID controllers are deployed in the photovoltaic system to track the maximum power point. The performance of the PID controller is influence by controlling parameters. In this paper, we have calculated the optimal parameter values of PID controller using the hybrid combination of GA-PSO algorithm. The proposed method Simulink is designed in MATLAB. After that, various parameters such as settling time, rise time, overshoot, peak time, undershoot, rotor speed, and power generated. The results show that the proposed method provides lower undershoot and settling time as compared to the existing method.
