Abstract

Performance and reliability of PV systems are facing major challenges in partial shading conditions (PSC). These drawbacks occur when the current mismatch and hot spot are brought about by an obstruction such as clouds, trees or buildings which shadow the module so that energy production is diminished and module damage may have occurred. This paper reviews different solutions to tackle PSC induced aging, such as array reassociation methods, improved MPPT algorithms or power electronics development. Layout reconfiguration techniques, such as Sudoku layout and Honeycomb layout, and dynamic switching have been demonstrated to achieve better tolerance to shading. Moreover, AI-supported MPPT algorithms such as PSO and GAs also present better global MPPT performances under partial shading. In addition, the implementation of advanced converter topologies has been important to ensure steady power generation under partial shading. The combination of these methods improves the PV system robustness, efficiency and life time against various shading situations. Subsequent studies need to concentrate on validation of the proposed techniques in a real and dynamic environment, hybrid MPPT approaches and combination of them with energy storage system for maximization of performance factors under diverse conditions.
