Hardware implementation of proposed and conventional PV array reconfiguration techniques to extract maximum power under various shading conditions

The unpredictability of partial shadowing impacts the solar photovoltaic system's performance. This results in mismatch losses, reducing the healthy PV module's power output. This paper proposes a new reconfiguration method to increase the power generation of an array by lowering the power losses. A new physical relocation technique named the magic matrix shifting (MMS) method has been introduced in this paper. This work uses MATLAB/Simulink to model a 36, 213w, 6 x 6 PV array construction. Under six different partial shading situations, the performance has been examined based on P-V, I-V characteristics, maximum power extraction, power loss, and percentage. For comparison purposes, conventional total-cross-tide (TCT) and six other reconfigurations, including sudoku (SK), optimum sudoku (OSK), zig-zag (ZZ), magic square (MS), sky-scraper (SS), and novel shade dispersion (NSD) have been considered.
