PV Array Topology Design and Performance Evaluation under Partial Shade Situations to Reduce Mismatching Power Losses

In this paper, photovoltaic (PV) array system is reconfigured using the Futoshiki game theory to enhance the global maximum power point (GMPP). A comparison is carried out with the conventional PV arrangements such as series-parallel (SP) and total-cross-tied (TCT) arrangements in terms of low power loss (PL), improved fill factor (FF), and execution ratio (ER) under partial shading cases. Overall, the present study proves that the reconfigured PV array using game theory Futoshiki has higher performance compare to conventional methods. The performance indices are measured in term higher GMPP, minimized PL, improved FF for proposed methods to prove the system feasibility under test scenarios. Present study is performed through MATLAB/Simulink study.
