Evaluating the efficiency of maximum power point tracking algorithms when the solar panels are shaded
Abstract
Currently, the research on solar power systems focuses on improving the performance, PV panel life. In the process of operation, one of the factors that have seriously affected the performance of PV panel life is the shading that is a topic of great research interest today. PV arrays get shadowed partially by passing cloud, building, trees.etc which cause P-V characteristics to appear multi peaks, which makes conventional maximum power point tracking algorithms do work not well, resulting in a decrease in the output power of this system. This paper focuses on modeling I-V and P-V characteristics of PV system under shading conditions and analyzes its effect on performance of maximum power point tracking algorithms based on Matlab – Simulink@ simulation.
