Abstract


The ever increasing demand for electric power can be met by enhancing loading capacity of the existing power lines. A consequence of this is to damp inter area power oscillations, In particular in multi machine power system. To damp the power oscillation s one of the effective solution is to use FACT Controllers besides controlling the steady state power flows in the lines also aids the damping of power oscillations. This paper gives The gains of Fractional order PI controller are optimized by using Particle Swarm optimization based optimization algorithm. The objective function in optimization problem is the power flow in the line where TCSC is placed. The effectiveness of the proposed controller in damping power oscillation improvement in dynamic performance of the power system is demonstrated by compare with the conventional PI controller. MATLAB/Simulink is used to simulate the Power System and TCSC Controllers.
