Abstract: This manuscript presents the simulation of a global maximum power point tracker (GMPPT) under partial shading effect for a solar photovoltaic module using MATLAB/SIMSCAPE. Conventional maximum power point tracking techniques such as fuzzy logic and “perturb and observe” do not guarantee the operation of the system on its maximum power point (MPP) and might result in a local power point under partial shading conditions. Photovoltaic characteristics, I-V and P-V curves, under partial shading conditions become more complex and generally result in more than one power peak. However, only the highest peak is considered as the global maximum power point (GMPP) while all others are considered local maxima's and hence, are (LMPP) This manuscript will focus on forcing the photovoltaic system to operate on its global maximum power point and hence, result in the maximum extracted power under shading and different environmental conditions.
