QFT-Based Load Frequency Controller Design with GA-Based Optimized Bias Coefficients

This paper presents the design method of a robust controller for the Load Frequency Control (LFC) problem, which is based on QFT (Quantitative Feedback Theory). Using this method, it is possible to obtain robustness against power system uncertainties. GA (Genetic Algorithm) has been used to optimize the frequency bias coefficients of power system, too. The simulation results of a two-area power system show that the system response with the proposed controller has a better transient response than the PI controllers.
