Damping Controller Design for TCSC using Theta-Particle Swarm Optimization Technique

H. Shayeghi, H.A. Shayanfar and A. Safari    

Abstract: In this study, optimal tuning of the Thyristor Controlled Series Capacitor (TCSC) damping controller in a multi-machine power system is proposed using Theta-Particle Swarm Optimization (θ-PSO) technique. The design problem was converted to an optimization problem with the time domain-based objective function for a wide range of operating conditions. The effectiveness of the proposed controller is demonstrated on a multi-machine power system through the nonlinear time-domain simulation and some performance indices studies in comparison with the PSO based damping controller. The results analysis revealed that the tuned θ-PSO based TCSC damping controller using the proposed method has an excellent capability in damping power system inter area and local oscillations in comparison with designed Classical PSO (CPSO) based TCSC controller and enhances greatly the dynamic stability of the power system.
