PV Array Reconfiguration Methods based on Game Theory to Eliminate Shading Effect during Non-uniform Irradiations: Experimental Feasibility

Abstract

An extensive investigation into the impact of shadowing conditions on photovoltaic (PV) systems (4×4 size) is presented in this paper. Two conventional PV module arrangements like Series-parallel (SP) and Total-cross-tied (TCT) are compared with a new mathematical puzzle such as Shape-Do-Ku based configuration under two realistic shading scenarios. In addition, the performance parameters such as power and voltage at global maximum power point (GMPP), power loss (PL), fill factor (FF), and execution ratio (ER) are assessed through MATLAB/Simulink modeling. The performance validation is through the experimental investigation, which proves the feasibility of the MATLAB/Simulink based results. Overall, the present study proves that the Shape-Do-Ku dependent results are better when compared to traditional PV module arrangements.
