IMPROVED PERTURB & OBSERVE MPPT METHOD USING PI CONTROLLER FOR PV SYSTEM BASED ON REAL ENVIRONMENTAL AND CLIMATIC CONDITIONS

Abstract

This paper covers the implementation of one of the most popular MPPT algorithm, Perturb & Observe Algorithm based on Proportional Integral (PI) Control for a typical PV system under real environmental and climatic condition. The environmental parameters were collected from an experimental setup made of Solar Meter and Temperature sensor to record Solar Irradiation and temperature respectively on a 50Watts Solar panel. The Experimental setup was mounted on the Campus of the University of Buea, Cameroon and data collected for one day in November which falls in the dry season at the site. The Real environmental parameters were injected into MATLAB/ Simulink were the system was investigated to show the enhancement of the tracking performance of the MPPT system coupled with PI controller
