| Summary: | This paper presents the effect of irradiance change in solar photovoltaic (PV) array interconnection schemes under partial shading conditions (PSCs) for optimal selection of PV interconnection schemes in order to extract maximum power (MP) from the PV array. A <inline-formula> <tex-math notation="LaTeX">$4{\times }4$ </tex-math></inline-formula> PV array is considered to examine the well-known PV interconnection schemes under different shading scenarios at distinct irradiance conditions. Simulation studies and experimental verification are carried out by considering a <inline-formula> <tex-math notation="LaTeX">$30~W$ </tex-math></inline-formula> PV panel to analyse the performance of the PV array under various dynamic conditions. Comprehensive analysis in terms of fill factor, output power and mismatching power loss is presented by considering different interconnection schemes under various shading scenarios and irradiance levels. From the simulation studies and experimental verification, it is observed that the irradiance magnitude has a significant impact on the PV power generation from array interconnection schemes under PSCs wherein the performance characteristics of the array interconnection schemes vary with the variation in irradiance levels. It is also identified that the irradiance factor needs to be considered as a design variable while selecting the optimal PV array interconnection schemes for maximum power extraction under PSCs. |
