FACTS-Based Solutions for Overload Mitigation and Voltage Regulation in Modern Power Systems

The growing demand for electrical energy has led to increased complexity in power generation and transmission systems, necessitating more effective and economical methods of operation. This paper addresses these challenges by leveraging Flexible Alternating Current Transmission System (FACTS) devices, which enhance the performance and control of power systems. Specifically, it introduces a novel sensitivity analysis-based method to identify the optimal placement of Thyristor Controlled Series Capacitors (TCSCs) and Static VAR Compensators (SVCs). The proposed approach is validated on IEEE 14-bus and IEEE 30-bus systems using Power World Simulator (version 18 Education), demonstrating its effectiveness in improving system stability and reducing power losses.
