Power System Quality Stability & Enhancement through the Application of Unified Power Flow Controllers (UPFC)

Abstract

Ensuring power system stability is crucial in modern electrical networks, especially with the increasing integration of unreliable renewable energy sources. Ensuring stability involves the ability of the system to withstand and quickly recover from interruptions like as breakdowns, variations in load, and unpredictability in generation. The Unified Power Flow Controller (UPFC) is an essential tool for addressing these challenges since it can simultaneously modify many transmission parameters, including voltage, phase angle, and impedance. The research used MATLAB and Simulink to create a model of a high-voltage transmission system using a Unified Power Flow Controller (UPFC). The aim was to evaluate the impact of the Unified Power Flow Controller (UPFC) on the stability of the electrical grid under various scenarios. The experimental setup included many scenarios, such as fault conditions, dynamic load fluctuations, and renewable integration that faithfully simulated the complex and constantly evolving environment of contemporary power systems. The major findings demonstrate that the UPFC significantly enhances voltage and frequency stability under all assessed circumstances. During instances of breakdowns, the Unified Power Flow Controller
