Abstract
Partial shading occurs when Photovoltaic panels don’t receive homogeneous solar radiation and this situation cause hotspot and power loss. In this study, a new SOS-WOA hybrid algorithm for maximum power point tracking and reducing power loss in photovoltaic systems under partial shading is proposed. In order to demonstrate the performance of the algorithm, the proposed system is simulated in Matlab/Simulink and analyzed for different scenarios. In addition, the algorithm has been compared with traditional ones in literature such as Perturb&Observe algorithm, Grey Wolf Optimization Algorithm and Symbiotic Organism Search Algorithm. Simulation results show that the hybrid Symbiotic Organism Search and Whale Optimization algorithm finds the maximum power point more accurately than the others. A higher efficiency is also obtained.
