Reconfiguring Multidimensional PV Arrays for Optimizing Output Power Under PSC

A solar photovoltaic (PV) power system consists of multiple modules connected in parallel and series to achieve a desired range of output voltage and current. However, these modules are highly vulnerable to partial shading condition(PSC), a common issue that can cause considerable power loss, hotspots, reduced system performance, and even permanent damage to the modules. To address these challenges, reconfiguration techniques are employed to redistribute shading intensity across the modules, reducing current mismatch and enhancing the system's power output. Despite their benefits, these techniques have a major limitation: they are predominantly designed for symmetrical or square arrays, which are uncommon in real-world applications. To increase system output power under different partial shading scenarios, this paper presents a Multidimensional Array Reconfiguration(MAR) technique for modules in asymmetrical arrays. The suggested methodology uses a one-time module arrangement and is simple, affordable, and easy to implement. In situations involving partial shading, it achieves lower power losses and improved system dependability.
