Study on Maximum Power Point Tracking for Photovoltaic Arrays Based on Fuzzy-Control Strategy

Abstract

The equivalent circuit diagram was established based on the internal structure of the photovoltaic cells, and a simulation model of the photovoltaic cells was built in Matlab/Simulink, which could simulate the output characteristics of the cells under different temperatures and light conditions. According to the separate simulation of the perturbation & observation and fuzzy-control algorithms, the results show that fuzzy control has better performance when dealing with this non-line system.
