This paper investigates and compares the enhancement of damping the power system oscillations via coordinated design of the power system stabilizer (PSS), Thyristor Controlled Series Compensation (TCSC) and Static Var Compensator (SVC) controllers. The design problem of FACTS-based stabilizers is formulated as an optimization problem. The proposed approach employs genetic algorithm (GA) for stabilizer parameters optimization. In this paper eigenvalue analysis method is used for small signal stability of single machine infinite bus (SMIB) system installed with PSS, TCSC and SVC. The proposed stabilizers are tested on a weakly connected power system with loading conditions. The eigenvalue analysis and non-linear simulation results are presented and to show and compare the effects of these FACTS-based stabilizers and reveal that TCSC-based stabilizers is much better than SVC-based stabilizers on the damping power system oscillations.
