Enhanced Power Generation from Photovoltaic Arrays Using a Novel Static Reconfiguration Circuit

Abstract

Partial shading conditions cause power losses of the photovoltaic (PV) array. This paper proposes a Bundle SuDoKu puzzle (Bundle SDKP) topology for static reconfiguration. To mitigate the shading effects in PV arrays and reduce the wiring length, the proposed topology adopts a combined set rule and the digit replacement procedure. Evaluation results demonstrate that the proposed Bundle SDKP features advantages, such as efficient shade dispersion, wiring loss reduction, simplification of power-voltage curves, and extracted power increase.
