Abstract

In this paper a new robust load frequency controller for two area interconnected power system is presented to quench the deviations in frequency and tie line power due to different load disturbances. The dynamic model of the interconnected power system is developed with new state variables without the integral and area control error. The frequency deviations and their derivatives are zero under steady state operation before and after the disturbance. The two area inter connected power system is subjected to a wide range of load disturbances and switching times. To validate the effectiveness of the proposed Fuzzy controller over the Proportional pulse Integral pulse Differential (PID) controller, Optimal controller and Genetic algorithm controller is compared. The results prove that the transient performance with the fuzzy controller placed in both the areas is better than those obtained by the other controllers. The problem is also solved by switching the controllers with certain time delay.
