A sliding mode output feedback saturation control for high penetration of wind in IPS with time-delay

This paper studies the problem of robust H

sliding mode control for interconnected power system with high permeability of wind power with actuator saturation and input delay. Actuator saturation is represented by sector boundary method. By constructing delay product augmented Lyapunov-Krasovskii functional, sufficient conditions for the asymptotic stability of the system are given. Then, the controller is designed according to the steady-state criterion to ensure the closed-loop system is asymptotically stable, and the performance index is H

. Finally, some numerical examples are given to illustrate the effectiveness and advantages of the proposed new design method.
