Abstract
This study presents coordinated control tuning of power system stabilizer (PSS) with series and shunt FACTS controllers. Here thyristor controlled series compensator (TCSC) and static synchronous compensator (STATCOM) based controllers are coordinated to enhance the damping of power oscillations and to improve voltage stability. The design of proposed damping controller is formulated as an optimization problem and the controller gains of a non-linear power system are optimized instantaneously using advanced adaptive particle swarmoptimization (AAPSO). Here the power system employed with PSS,TCSC and STATCOM. To compare the performance of proposed controller four different control schemes employed on test power system. Finally, the proposed coordinated controller performance is discussed with time domain simulations. Wide ranges of loading conditions are employed on the test system to test the robustness of proposed coordinate controller and the simulation results are compared with different control schemes.
