Abstract
Shading of photovoltaic panels is one of the most prevalent causes of power decrease.A partial shading condition (PSC) creates multiple distinctive peaks in the power-voltage (P-V) curve.Reconfiguration distributes partial shade on a complete array.It reduces the mismatch power losses and boosts the power generation of the solar photovoltaic (SPV) array.This paper proposes a novel static PV array reconfiguration method named the novel shade distribution (NSD).The performance of the proposed method has been evaluated and compared with the best conventional total-cross-tide (TCT) method and available reconfiguration(AR) methods, sudoku (SK), optimal sudoku (OSK), and zigzag (ZZ).The performance has been investigated under eight partial shading conditions with five performance evaluation parameters.This paper validates the performance of the proposed method through MATLAB/Simulink and hardware experimentation.
