Modelling and Simulation of Perturb and Observe Algorithm on Solar PV Water Pumping System using Different Controllers in MATLAB/Simulink

Abstract

This paper deals with the Perturb and Observe algorithm on a Photovoltaic System using different Controllers in MATLAB/Simulink. The Photovoltaic System is depends on the mathematical equations. The P & O algorithm is the Maximum Point Tracking Technique (MPPT) to track the maximum power point. A high level boost converter is used between solar panel and the PWM inverter. The DC voltage is maintained constant by controlling the duty cycle of boost converter. Three phase Voltage Source Inverter (VSI) is maintain constant supply to PMSM under change in solar irradiation to regulate discharge of water. The performance of system employing PMSM drive with PI controller and fuzzy logic controller is analyzed. The current and voltage ripple harmonics will be reduced and THD (total harmonic distraction) also reduced. The Modelling and Simulation of Perturb and Observe Algorithm is done by using Different Controllers in MATLAB/Simulink.
