Photovoltaic Generator power Enhacement Competence using square technique

Abstract

Recently, the increasing interest in solar energy has led to the development of large scale solar arrays. Although the most commonly used TCT (total cross-connection) interconnection scheme minimizes mismatch losses. However, the shading in large PV arrays can significantly reduce the power output and cause multiple power peaks in the P-V characteristics. In order to avoid the problem of multiple peaks, PV arrays are reconfigured using electrical or physical reconfiguration techniques. For this purpose, the physical repositioning method proved to be effective and economical in achieving better shadow dispersion, as it neither requires complex switch arrangements or expensive controllers for reconfiguration compared to electrical methods. Therefore, this graduation thesis introduces an innovative Competence Square (CS) technology for the physical rearrangement of photovoltaic panels in a TCT interconnection scheme.
