Comparative Analysis of Various Reconfiguration Techniques for Partial Shading Conditions in Solar Photovoltaic Systems

This project presents a comprehensive comparison of voltage, current, power, and fill factor for three different photovoltaic array reconfiguration techniques: Series-Parallel (SP), Total Cross-Tied (TCT), and Hybrid TCT-SP. The study investigates the performance of these techniques under various partial shading conditions. The focus is on identifying the most effective method for power enhancement in photovoltaic arrays subjected to shading. Experimental results demonstrate that the hybrid TCT-SP reconfiguration technique consistently outperforms the SP and TCT techniques across eight different shading conditions. The hybrid technique exhibits superior power enhancement capabilities, as evidenced by increased voltage, current, power, and fill factor. This research provides valuable insights for optimizing the performance of photovoltaic arrays under partial shading conditions, contributing to the advancement of renewable energy systems.
