Harmonics, Power Quality, Phase Locked Loop, Unified Power Quality Conditioner (UPQC) and Doubly Fed Induction Generator(DFIG)

The incorporation of renewable energy sources into the electrical grid presents difficulties, particularly with the variable nature of wind energy systems due to wind fluctuations. Voltage instability in power networkSIMULINKuse sag, swell, harmonics, and flicker, among other problems. To address these issues, the introduction of Flexible AC Transmission System (FACTS) devices is required, with the Unified Power Quality Conditioner (UPQC) emerging as a reliable option. This research critically explores the use of UPQC in a wind system based on a Doubly Fed Induction Generator (DFIG), notably under unbalanced and distorted load situations. The analysis focuses on this situation in order to improve knowledge and offer appropriate methods to ensure the stability and dependability of power networks, particularly in the context of renewable energy integration. The UPQC is designed using a revolutionary synchronous reference frame control mechanism. The model is built using the MATLAB/SIMULINK platform, and the results show that the suggested strategy is effective in decreasing power quality concerns.
