Transposition Reconfiguration Technique for Improved Power Generation from Photovoltaic Arrays under Non-Uniform Irradiance

Due to partial shade of the PV modules, the photovoltaic array's output power substantially reduces. Partial Shading Condition (PSC) happens when some PV modules receive reduced insolation as a result of the shadow cast by surrounding trees, buildings, and passing clouds, among other factors. In addition to reducing output, the PSC situation caused several peaks in the photovoltaic array's Power-Voltage (P-V) characteristics. The peak having the greatest power among all the peaks is known as the Global Maximum Power Point (GMPP). Partial shading may cause Maximum Power Point Tracking (MPPT) approaches to trap at a local minimum; to prevent this, one should evenly spread the shade across all the rows. The placement of the shaded PV module and the PV arrangement have the most effects on PSC. The reconfiguration of PV modules is one of the methods for minimizing the impact of PSC. In order to rearrange PV modules in a PV array once, a Transposition Reconfiguration technique (TRT) was put forward in this study. The performance of the suggested TRT is evaluated against SuDoKu and Optimal-SuDoKu Reconfiguration methods.
