Performance Evaluation of Spider Web Tie (S-B-T) PV Panel Configuration to Reduce PV Mismatch Losses

Abstract

In non-uniform conditions, the power curve of a solar plant can vary significantly, which can affect the performance of the system. In such conditions, the configuration of the panels can help reduce the mismatch losses. Although dedicated electronics may be helpful in reducing a panel's mismatch, the panel configuration is a recent solution that can also reduce a panel's overall power consumption and mismatch losses. Hence in this paper Sider Web Tie (S-B-T) PV panel configuration is proposed. A test case of 5 X 5 200 W PV panel is considered. The proposed S-B-T PV configuration is implemented under real time PSC's in comparison with Series-Parallel (S-P), Total Cross-Tied (T-C-T), Triple-Tied (T-T), Bridge-Link (B-L) configurations. The factors such as PV mismatch losses, Max. current and voltage, OC Voltage, SC Current that influence the performance of the system are investigated. In all the cases proposed Spider Web Tie (S-B-T) PV configuration exhibits the superior performance.
