Design of integral controller for Load Frequency Control of Static Synchronous Series Compensator and Capacitive Energy Source based multi area system consisting of diverse sources of generation employing Imperialistic Competition Algorithm

This paper presents the design of integral controller for Load Frequency Control (LFC) under deregulated environment having diverse sources of power generation employing Imperialistic Competition Algorithm (ICA). Static Synchronous Series Compensator (SSSC) along with Capacitive Energy Storage (CES) 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 Imperialistic Competition Algorithm based system employing Static Synchronous Series Compensator and Capacitive Energy Source has better dynamic performance over the system without these parameters.
