In this study an optimal 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. In
classical LFC problems, PI type controllers are used to control of system. But due to some disadvantages of
the PI type controllers, the researchers are toward finding a better control scheme. Although many different
advanced method have been carried out to LFC problem, but the industries are willing to use simple PI
controllers. In this scope, this paper presents IP type controller for LFC problem. The parameters of the
proposed IP controller are tuned using Harmony Search (HS) method. A two-area electric power system with
a wide range of parametric uncertainties is given to illustrate the proposed method. To show effectiveness of
the proposed method and also comparison purposes, a PI type controller optimized by HS is also designed. The
simulation results visibly show the validity of IP controller in comparison with PI controller.
