Abstract :This paper aims at investigating the problem of Load Frequency Control insert ignore into journalissuearticles values(LFC); in interconnected power systems in order to obtain robustness against uncertainties. A design method for a robust controller, based on Quantitative Feedback Theory insert ignore into journalissuearticles values(QFT);, has been presented in this paper. For a two-area power system, the simulation results show that the system response with the proposed QFT controller exhibits transient response beyond PI controllers. It is also shown that the transient response of the tie line power can also be improved.
