摘要：
In this paper, the strategy of a single area power system sliding mode load frequency control is proposed for the single area power system with time-delay uncertainty, parameter uncertainties and load disturbance. Firstly, to design sliding mode surface, switching function is selected properly to guarantee the time-delay power system has a stable sliding mode. Secondly, sliding mode controller is designed to guarantee the state trajectory of power system reach to sliding mode surface in finite time. Finally, to build a simulation example through the platform of Matlab/Simulink, its robustness and control performances of the proposed controller are examined when the power system is at different operating points and under GRC. The simulation results show that time delay system with sliding mode controller has a quicker response and better robustness than the one without sliding mode controller.
