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.

I. Introduction

Now a days, electricity generation using photovoltaic (PV) cells is gaining popularity. Fundamentally, PV cell uses solar insolation for electrical energy generation [1]. The output power from PV cell not only depends upon the environmental factors but also on the impedance matching with load. Solar energy is among the best accessible alternative to conventional energy resource to generate electrical energy for nations along equatorial region like India as it is available all around the year. Worldwide to accomplish the goal of decreasing the energy deficit, wide utility of PV cell technology for energy generation is getting popular. Some notable points of interest of solar energy are [2]:- •

PV cell is a static device.

•

PV cells are modular, and requires no maintenance for reasonable amount of time.
