Enabling PID and SSSC for load frequency control using Particle Swarm Optimization

Rapid human population has led to increasing number of load demand. This load demand increased could potentially lead to instability of power system such as frequency stability. It is well known that governor has a significant role in controlling frequency on the generator. Generally, the governor usually used simple integral controller as the controller. However, with increasing number of load and rapid load changing, integral control only is not enough to handle the problems. Hence, deployment additional devices such as flexible alternating current transmission systems (FACTS) devices and changing the governor controller to PID controller is crucial. This paper proposed an enhancement of load frequency control using PID controller and Static Synchronous Series Compensator (SSSC). A Particle Swarm Optimization (PSO) is used as an optimization method to find the best parameter. Two area power system are used as a test system to analyze the performance of system with proposed method (PID and SSSC based on PSO). To examine the performance of the system with or without proposed method. From the simulation, it is found by using PID and SSSC based on PSO the frequency performance of the system is enhanced.
