Sažetak:
In this paper an optimal load-frequency controller for nonlinear power system is proposed. The mathematical model of power system consists of one area with several power plants, a few concentrated loads and transmission network, along with simplified models of neighbor areas. Firstly, a substitute linear model is derived, with its parameters being identified from the responses of the nonlinear model. That model is used for load-frequency control (LFC) algorithm synthesis, which is based on discrete-time sliding mode control. Due to non-minimum phase behavior of hydro power plants, full-state feedback sliding mode controller must be used. Therefore, an estimation method based on fast output sampling is proposed for estimating unmeasured system state and disturbance. Finally, the controller's parameters are optimized using genetic algorithm. Simulation results show that the proposed control algorithm with the proposed estimation technique can be used for LFC in nonlinear power system.
