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 AGC problem. So the traditional AGC system is modified to take into account the effect of bilateral contracts on the dynamics. Simulation results show that the simulated annealing based system employing Static Synchronous Series Compensator has better dynamic performance over the system without SSSC.
