Comparative analysis of various reconfiguration strategies of PV array in partial shading conditions: a review

Abstract

Photovoltaic system performance depends on factors like bypass diode topology, array size, arrangement, and shading intensity. Partial shading causes mismatch losses and reduced power production. Though many methods address this, they may not fully optimize power. Reconfiguring PV modules offers a promising solution to minimize power loss. In this paper, major Static and Dynamic reconfiguration strategies have been discussed. The methodology, benefits, and limitations of each approach are compared and evaluated. The research set out to compare and contrast the effectiveness of static and dynamic reconfiguration approaches with regards to energy output, shading losses, and mismatch losses. The results showed that dynamic reconfiguration was more effective in reducing shading losses and increasing energy yield compared to static reconfiguration. This article aims to help researchers and readers in gaining an understanding of the available reconfiguration strategies and factors that affect their selection. Overall, this article is a valuable resource for researchers, engineers, and professionals working in the field of renewable energy, particularly in the area of PV systems.
