Continuous Reconfiguration Framework for Photovoltaic Array under Variable Partial Shading Conditions: Heuristic-Based Algorithms with Optimizing Switching Operation

The operation of the photovoltaic (PV) system under partial shading conditions (PSC) is complicated since output characteristic PV profoundly affected by heterogeneous irradiance PSC. This paper proposes a dynamic reconfiguration framework to tackle PSC in array. Continuous array cloud-induced considered developing an emulator moving cloud. In addition, Particle Swarm Optimization and Rao algorithms are improved obtain optimal configuration switching enhanced simultaneously considering total times highly active switches. simulation results on 9×9 demonstrate effectiveness proposed terms reducing number local maximum power points power-voltage characteristic, enhancing output, relieving stress different
