The Combined Effect of Current Boosting and Power Loss on Photovoltaic Arrays under Partial Shading Conditions

This study proposes a novel technique for improving the performance of photovoltaic (PV) arrays under Partial Shading Conditions (PSCs). A 4×4 solar PV array with 16 panels was considered. Bridge-Linked (BL), Total Cross-Tied (TCT), Honey Comp (HC), One Cross-Link (OCL), and Two (TCL) were among topologies interest. First, combined effect connecting switches partial shading on studied. Then, power loss/gain caused by reconfiguring structure from Series-Parallel (SP) to other schemes investigated. Finally, method boosting current into is proposed reduce PSCs-related losses in switches. The results show that number topology plays an important role determining gain or loss at different levels. TCT HC outperformed others terms improvement when PSCs considered without boosting. true levels irradiation exposure. SP optimal level greater than 900W/m2 less 200W/m2. boosted array, 108%, certain PSCs.
