Design of Integral Controller for Static Synchronous Series Compensator Based Hydrothermal System under Deregulated Environment Employing Genetic Algorithm

摘要

This paper presents the design of integral controller for Automatic Generation Control (AGC) of hydrothermal system under deregulated environment employing genetic algorithm (GA). Static Synchronous Series Compensator (SSSC) has also been proposed to further increase the dynamic performance of the system in terms of peak time, overshoot and settling time. The concept of soft computing techniques greatly helps in overcoming the disadvantages posed by the conventional controllers. Open transmission access and the evolving of more socialized companies for generation, transmission and distribution affects the formulation of LFC problem. So the traditional LFC system is modified to take into account the effect of bilateral contracts on the dynamics. Simulation results show that the genetic algorithm based system employing Static Synchronous Series Compensator has better dynamic performance over the system without SSSC.
