In this paper, we are considered various possible disturbance conditions in order to design controller, H<SUB>∞</SUB> optimal controller is successfully designed to control in such as situations. To do this, we are determined weighting function and design parameter γ to method of trial and error by Glover-Doyle algorithm. To compare with H<SUB>∞</SUB>-PSS and conventional-PSS which is applied in nominal system and load variations, the dynamic characteristics of H<SUB>∞</SUB>-PSS controller was verified which has a good response.

This paper designs the optimal PID controller for load frequency control on 2-area power system. Genetic algorithm is utilized to optimize parameters of PID controller which is applied to power system. Using two-point crossover, uniform crossover and one-point crossover, Search performance of genetic algorithm with each crossover method is considered. In case of load variation in 1-area, the dynamic characteristic of power system is considered. The simulation results show that the proposed PID controller is better control performance than PID controller using Ziegler-Nichols method.
