Abstract
Since chaotic oscillation in power system causes serious damage to the stability of the whole system, a dynamic surface sliding mode control strategy is proposed for the seven dimensional chaotic power system. Firstly, chaotic oscillation behavior in the power system was analyzed, and the existence of chaotic attractors was demonstrated. Then, the construction process of coupled dynamic model of controlled power system with energy storage devices was given. Chaos control problem was finally reduced to the control of three dynamic subsystems with strict feedback form, and corresponding dynamic surface sliding mode controllers were designed for them. Due to the characteristics of the controlled system, introducing sliding mode control in the dynamic surface control method can reduce the design steps of dynamic surface controllers and the complexity of stability analysis of closed-loop system. Stability analysis proves that closed-loop system can achieve uniformly ultimately bounded stability. Finally, the effectiveness of designed controllers is verified by numerical simulation.
