Co-ordinated tuning of PSS with TCSC damping controller through advanced adaptive PSO for a multi-machine power system

This study presents coordinated control tuning of power system stabilizer (PSS) with thyristor controlled series capacitor (TCSC). The design of proposed coordinated damping controller is formulated as an optimization problem and the controller gains are optimized instantaneously using advanced adaptive particle swarm optimization (AAPSO). Here the multi-machine power system employed with PSS and TCSC is considered. The coordinated tuning among the damping controllers is performed on the non-linear power system dynamic model. Finally, the proposed coordinated controller performance is discussed with time domain simulations. Different loading conditions are employed on the test system to test the robustness of proposed coordinate controller and the simulation results are compared with four different control schemes.
