Improved power generation from PV array operating in partial shading scenarios by shade dispersion using Sumoku reconfiguration

Photovoltaic (PV) arrays can lose significant power due to partial shading. This occurs when some solar cells in the array are shaded while others are not. The shaded cells produce less power, which can reduce the overall output of the array. Enhancing power generation from PV arrays under partial shading conditions can involve restructuring the connections among solar cells as a potential solution. This action can scatter the shading and enhance the overall power output of the array. This research paper presents a novel approach to reconfiguring PV arrays to maximize power extraction from solar energy using the Sumoku technique. The efficacy of the proposed technique is determined by comparing it to Total Cross Tied (TCT). The comparative study involved simulations and analyses of the algorithms’ efficiency in achieving maximum power extraction. The results indicate that the Sumoku technique outperforms the other algorithms in enhancing PV array reconfiguration for optimal power generation. The Sumoku reconfiguration technique achieved a maximum global maximum power (GMP) enhancement of 25.9% to 34% compared to the TCT configuration.
