Abstract：Automatic generation control (AGC) is very important to power system operation. But for reducing its action number, it should be set a dead band for governor, as a result to increase its complexity. In this paper a new simulation model considering the effect of governor dead band nonlinearity by using the describing function approach for automatic generation control studies of two-area system is proposed. And an improvement particle swarm optimization algorithm used to optimum the parameters of the integral controller and area frequency deviation coefficient. Through the simulation analysis of the automatic generation control system of two-area interconnected power system, the results show that the new proposed model can actually enough to express the performances of the automatic generation control system, and that this method is effective.
