Study and analysis of partial shading effect on power production of a photovoltaic string controlled by three different MPPT techniques: P&O, PSO and ANN
Partial shading occurs when some of the solar panels are exposed to reduced irradiation. Partial shading can lead to creating peaks and troughs in power production. The goal of this study is to compare the effect of partial shading on the capacity of maximum power point tracking (MPPT) methods, to find the global maximum power point. To this end, the study focuses on performance simulation and discussion of Perturb and Observe (P&O), Particle Swarm Optimization (PSO), and Artificial Neural Network (ANN) controls. Analysing the three MPPT controller's results, in
