Exploring the PV Topologies in Comparison with Loshu Reconfiguration: Estimate Output Power

Mismatch losses, which degrade the performance of individual photovoltaic (PV) modules, significantly lower the electricity generated by the PV array. These losses, which are mostly caused by the partial shade condition, are caused by passing clouds, poles, birds, being close to buildings, etc. There are several ways to lessen the issues with partial shading. Reconfiguration, which involves shifting PV modules around in an array to spread out the effects of partial shadowing and increase maximum power production, is one of the most efficient ways. This research presents a Loshu reconfiguration pattern for a 9×9 Total-Cross-Tied (TCT) PV array to enhance maximum power production under partial shade situations and compares it to other techniques like Series Parallel (SP), Bridge Link (BL), TCT configuration, and Sudoku reconfiguration. The fundamental objective of this method is to keep the same electrical connections while arranging the PV modules in a TCT array in a Sudoku pattern. With a variety of current PV array configurations, the performance of the suggested pattern is evaluated in terms of mismatch losses (ML), fill factor (FF), and execution ratio (ER). The results of this article imply that the Loshu PV array configuration will boost the global maximum power under all shading circumstances.
