SSSC and TCPS Based Hydrothermal System to Improve Dynamic Performance Via FABFM

This paper investigates Automatic Generation Control (AGC) of hydrothermal system under deregulated environment. A novel dual mode controller is used in AGC and the optimization process is done by Fuzzy Adaptive Bacterial Foraging Method (FABFM). The dynamic performance of the system with regard to peak time, overshoot and settling time has been improved by means of Flexible AC Transmission Systems (FACTS) devices like Static Synchronous Series Compensator (SSSC) and Thyristor Controlled Phase Shifter (TCPS). There might be problems with present controllers to be solved by soft computing techniques. Some factors influencing the formulation of AGC problem are open transmission access and the evolving of more socialized companies for generation, transmission and distribution. Therefore, the effect of bilateral contracts on the dynamics should be considered in modern AGC systems. Results reveal that using dual mode controller based on FABFM plus SSSC and TCPS has much more dynamic efficiency than the system with integral controller.
