Performance Evaluation of PV Panel Configurations Considering PSC’s for PV Standalone Applications

Abstract

One of the major concerns for continuous solar photovoltaic (PV) generation is partial shading. The movement of clouds, shadow of buildings, trees, birds, litter and dust, etc., can lead to partial shadow conditions (PSCs). The PSCs have caused inconsistent power losses in the PV modules. This leads to a shortage of electricity production and the presence in the PV curve of several peaks. One of the simplest solutions to PSC’s is the PV configurations. The objective of this paper is modelling and simulation of solar PV system in various shading scenarios for KC200GT 200 W, 5 x 5 configurations that includes Series/Parallel (SP), Total-Cross-Tied (TCT), Triple-Tied (TT), Bridge-Link (BL) configurations. Real time PSC’s such as corner, center, frame, random, diagonal, right side end shading conditions are evaluated under all PV array configurations. A comparative analysis is carried out for the parameters such as open circuit voltage, short circuit current, maximum power point, panel mismatch losses, fill factor, efficiency under all PV configurations considering PSC’s. From the comparison analysis best configuration will be presented.

Performance Analysis of Maximum Power Point Tracking for Grid-Photovoltaic System

“…Consequently, the online tracking of the maximum power point (MPPT) is crucial for optimizing the performance of PV systems. Efforts to address these challenges through research and technological advancements have been documented extensively in the studies [3][4][5][6][7][8]. To maximize power extraction from the PV generator, a sophisticated approach involves employing an optimal algorithm for Maximum Power Point Tracking (MPPT) in conjunction with loop control mechanisms utilizing a Proportional Integral (PI) controller.…”
