Title: A Hybrid Genetic-Simulated Annealing Approach to TCPS based Hydrothermal System under Open Market System
Authors: C. Srinivasa Rao and S. Siva Nagaraju and P. Sangameswara Raju
Abstract: This paper presents the analysis of Automatic generation control (AGC) of a two-area interconnected hydrothermal system with Thyristor controlled phase shifter (TCPS) in series with the tie-line under open market system. It also involves the optimization of integral controller employing a hybrid approach of modified Genetic algorithm and Simulated Annealing method (HMGASA) modified genetic algorithm method. 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 two-area system is modified to take into account the effect of bilateral contracts on the dynamics. It is possible to stabilize the system frequency and tie-power oscillations by controlling the phase angle of TCPS which is expected to provide a new ancillary service for the future power systems. A control strategy using TCPS is proposed to provide active control of system frequency. Gain settings of the integral controllers without and with TCPS are optimized using the HMGASA technique following a step load disturbance in either of the areas. Analysis reveals that a TCPS is quite capable of suppressing the frequency and tie-power oscillations effectively as compared to that obtained without TCPS
