Control Strategy for Load Frequency Control in Power Systems with Electric Vehicle Charging Stations

The increasing usage of electricity in modern times has led to a rise in power system loads and a rapid increase in pollution caused by petrol and diesel vehicles. As a result, many individuals are transitioning to electric vehicles (EVs). However, charging EVs for extended periods can significantly impact the load on power systems, leading to frequency fluctuations that may damage the system. To mitigate these disturbances in interconnected systems, Static Synchronous Series Compensator (SSSC) is employed as a controller. SSSC is a Flexible AC Transmission System (FACTS) device that effectively reduces deviations in transmission lines, ensuring a steady-state frequency. This research paper aims to reduce frequency deviations caused by uncertain loads from EV charging stations by optimizing SSSC parameters using the RAT optimization technique within the MATLAB environment.
