Performance Evaluation of PV Array Systems Under Partial Shaded Situations to Minimize Mismatching Power Losses

Abstract

In-depth examination of the effects of shadowing on photovoltaic (PV) performance in terms of power losses (PL) is presented in this paper. Partially shaded areas, for example, are studied to determine the best arrangements for reducing their negative effects. When it comes to arranging PV modules, conventional methods such as series-parallel (SP) and total cross-tied (TCT) have been compared to advanced electrical arrangements based on the Ken-Ken puzzle, symmetric matrix, magic square, and symmetric matrix. As a result of this shading capability, PV systems can achieve higher fill factors (FF), global maximum power points (GMPP), minimized PL and higher execution ratios (ER). The MATLAB/Simulink environment is used to study and test the simulation of PV array configurations.
