Damping of Power System Oscillations Using GA and GOA Optimized SSSC Based Controller

Growth of energy sector is one of the major factors in empowering the nation. And strengthening of power system is done by enhancing system reliability, security and quality. The main area to focus on is stability of the power system as it maintains the voltage and frequency of the system to a desired level. This paper presents a Single Machine Infinite Bus system with a Static Synchronous Series Compensator (SSSC) based supplementary damping controller in addition with PSS (Power System Stabilizer). The most favorable values of the SSSC based supplementary controller is determined using Genetic Algorithm and Grasshopper optimization Algorithm and comparison of both the optimization techniques is made. The coordinated design of controllers, thus formed is studied considering different fault conditions and system response against these fault conditions are analyzed.
