Abstract
This paper provides a linearized model of single machine infinite bus power system with a Thyristor controlled series compensator (TCSC) controller for small signal stability studies. Further, this paper gives individual & coordinated design for performance comparison of TCSC & Power system stabilizer (PSS). Using the linearized system model & Particle swarm optimization algorithm the parameters of TCSC & PSS controllers are optimized & interactions among them are minimized. The proposed control scheme on analysis reveals that the coordinated control of TCSC & PSS with lead -lag controller gives better dynamic performances as compared to with only PSS.
