摘要

The integration of renewable energy and networked communication brings instability of frequency of multi-source interconnected power systems, especially under aperiodic denial-of-service attacks and actuator saturation. This paper proposes predefined-time sliding mode control to mitigate frequency deviations caused by aperiodic denial-of-service attacks. The proposed method realizes stability within a predefined-time independent of the initial states and the control parameters. Compared with sliding mode control and fixed-time sliding mode control, the designed controller has faster convergence and stronger robustness. Simulation results on a two-area power system are given to demonstrate the effectiveness of the proposed method under different control parameters.
