Reconfiguration Study of Solar PV Cells to Minimize Partial Shading Effect

Non-uniform irradiation causes a photovoltaic (PV) cell to deliver much less electricity, which results the generated unit decreased and further was impairing the overall system performance. The shading pattern and array configuration type are selected to determine the output power reduction rather than the shading area. The literature has described numerous ways to lessen partial shadings. The suggested solutions might not, however, be able to maximize power to the fullest extent feasible. Therefore, a promising strategy based on reconfiguration strategy that is reconfiguring the PV unit within the PV assortment to boost utmost power at an advanced level is needed to compensate for these power losses. The most advanced reconfiguration methodologies for PV units to maximize control under partial shade and mismatch circumstances are presented in this research. Furthermore, this study discusses the difficult problems associated with the circuit realization of both static and dynamic arrangements on strategies. While it is evident that dynamic reconfiguration approaches come at a higher cost, SuDoKu approaches are a more efficient way to offset the impacts of mismatch and partial shadowing in photovoltaic arrays.
