Power Quality Analysis of Fuzzy Logic Controller Based Distributed Generation System with UPQC

This paper explores the integration of renewable energy sources into current power systems as a means to enhance energy efficiency, reduce emissions of greenhouse gases, and tackle the issue of climate change. A variety of renewable energy sources, including wind, solar panels, and solid oxide fuel cells, are integrated into the proposed hybrid system. The following challenges (Maximum power production) must be overcome, and effective control algorithms must be devised when renewable energy sources generate electricity. This paper presents a comprehensive power quality analysis of a Fuzzy Logic Controller (FLC) based Distributed Generation (DG) system integrated with a Unified Power Quality Conditioner (UPQC). The proposed system aims to enhance power quality by mitigating issues such as voltage sags, swells, and harmonics, which are common in distributed generation environments. A detailed MATLAB/SIMULINK model is developed to promote the integration of hybrid renewable energy sources to enhance the performance of the Fuzzy Logic Controller (FLC) and the Unified Power Quality Conditioner (UPQC) under diverse operational conditions. Significant improvements in power quality are demonstrated by the results obtained quality, evidenced by reduced Total Harmonic Distortion (THD) and stabilized voltage levels. This study highlights the effectiveness of integrating FLC with UPQC in DG systems, providing a robust solution for maintaining power quality in modern power networks. The system results are validated using the IEEE 1547 and IEEE 519 standards to demonstrate the System's effectiveness.
