Power Enhancement of Solar PV Array Under PSC by Puzzle Based Arrangement

Abstract

The main hindrance in the PV array that reduces its effectiveness is partial shading. During partial shading condition (PSC), PV array obtain non-uniform irradiance, resulting in mismatch loss in series connected PV modules. To compensate for the consequences of partial shading on the PV array, physical relocation techniques are used. This paper, proposed a puzzlebased arrangement (PBA) physical reconfiguration technique. The sole motive of this work is to reduce the effect of partial shading and to enhance the power of the PV array. The outcomes of the proposed PBA physical reconfiguration is analysed and evaluated against the conventional array configurations under different shading patterns. The outcomes of all the configurations are investigated in MATLAB Simulink and analysed on the basis of Fill Factor, Mismatch Loss and Global Maximum power.
