Evaluation of MPPT Algorithms for PV System under Partial Shading Conditions

Abstract

The harmful impacts of fossil fuels have made us adopt renewable energy sources which do not replenish upon more usage. The renewable energy sources like solar PV system provide many benefits, including green and clean energy. At the same time, solar PV panels suffer from low output power when subjected to partial shading. Several Maximum Power Point Tracking (MPPT) algorithms have been proposed in the literature to tackle this problem. Choosing an appropriate algorithm to track the maximum power point is of paramount importance as it improves the efficiency of the PV system by a significant margin. This paper focuses on evaluating and comparing various MPPT algorithms that fall under different categories such as conventional, soft computing and hybrid methods. These algorithms are simulated and tested on a partially shaded PV system for various performance parameters in MATLAB/Simulink environment.
