Su-Do-Ku Game Puzzle for Improving Shade dispersion factor on PV Array Systems under PSCs: Experimental Validation

Partial shading conditions (PSCs) are the most significant impediment to photovoltaic (PV) system performance. The cause of PSCs is due to high rise buildings, passing clouds, overcast weather, and telecom towers etc. in urban areas. The conventional PV array, e.g., Total cross-tied (TCT) configuration, is utilized to show the effectiveness of PSCs. In addition, integer number placement of Su-Do-Ku model is introduced to reduce the impact of shading. Furthermore, a comprehensive comparison carries out to reduce the shading impact on PV array systems. This elaborated comparative study analysis is based on distinguished performance parameters such as, short-circuit current ($I_{SC}$), open-circuit voltage ($V_{OC}$), power and voltage at global maximum power point (GMPP), minimized power loss (PL), and fill factor (FF) are measured to show the efficient behaviour of new approach. Moreover, MATLAB/Simulink analysis proves the efficiency of the suggested method by reducing the many peaks and improving the resultant power. An experimental study was introduced to validate the obtained results and confirm the practicability of the present study.
