Optimal Coordination of TCSC and AGC to Enhance Dynamic Stability of Interconnected Power System

Th e prominent function of AGC is appropriately maintenance the system frequency along with the tie line flow at their scheduled amounts in ordinary operation as well as small perturbations. TCSC, one of series FACTS devices families, can significantly enhance the damping ratio during contingencies conditions, i.e. transient and dynamic fault occurrences. Th is paper deals with the effect of a TCSC in facing the load perturbation in a deregulated two interconnected area. Furthermore, coordination scheme is optimally performed between AGC and TCSC using GA in order to enhance dynamic stability of interconnected power system. All the simulation studies have been performed in MATLAB software. Th e simulation results present high performance of TCSC as well as its coordination with AGC in order to improve the load flowing performance of the interconnected power system.
