Photovoltaic Cells Rearrangement using Meta-Heuristic Optimization Techniques for Shade Dispersion

Uneven illumination diminishes the proficiency of Photovoltaic(PV) array due to variation of current in a PV module. This paper proposes the shade dispersion on 6×4 PV array using meta-heuristic techniques to mitigate effect of uneven illumination. Firstly, some predefined combination of PV interconnection has been studied and among those configurations the one which outperforms others is further considered for shade dispersion using meta-heuristic techniques. Here, two diverse meta heuristic techniques are employed viz., Particle Swarm Optimization(PSO) and Genetic Algorithm(GA) for shade dispersion on PV array.
