MPPT Techniques of the Solar PV under Partial Shading

During the last decade, photovoltaic energy has become a reliable source of energy with a production rate and a constantly decreasing maintenance cost thanks to the progress of technology and the evolution of the photovoltaic market. Literature offers many MPPT algorithms that can go near the maximum power point. The characteristics of the photovoltaic panel under partial shade include several local MPPs and one global. Classical maximum power point tracking algorithms cannot achieve overall MPP. So, this work aims to study the behavioral performances of two (02) optimization techniques. They were developed to extract the overall MPP from the partially shaded PV. Maximum power point tracking performances based on PSO and P&O are evaluated for different partial shading models based on Matlab / Simulink.
