Abstract :In this paper, the optimal design of supplementary controller parameters of a unified power flow controller insert ignore into journalissuearticles values(UPFC); to damp low-frequency oscillations in a weakly connected system is investigated. The individual design of the UPFC controller, using the imperialist competitive algorithm insert ignore into journalissuearticles values(ICA); technique over a wide range of operating conditions, is discussed. The effectiveness and validity of the proposed controller on damping low-frequency oscillations is tested through a time-domain simulation and eigenvalue analysis under 4 loading conditions and a large disturbance. The simulation results, carried out using MATLAB/Simulink software, reveal that the tuned ICA-based UPFC controller has an excellent capability of damping power system low-frequency oscillations and greatly enhances the dynamic stability of the power systems.
