Simultaneous Coordinated Design of TCSC-Based Damping Controller and AVR Based on PSO Technique

Power system is a nonlinear system that requires accurate and robust control to improve power system stability following the occurrence of disturbance. In order to damp out oscillations, coordinated design problem of TCSC-based damping controller and AVR is formulated as an optimization problem. PSO technique has been employed to solve the optimization problem. Dynamic performance of these controllers has been appraised over a wide range of loading conditions under sever disturbance in SMIB power system. The non-linear time-domain simulation results suggest that the robustness of simultaneous coordinated design of these devices to enhance power system dynamic stability.
