Abstract

Based on an event-triggered mechanism, load frequency control of multi-area interconnected power systems under aperiodic denial-of-service (DoS) attacks is studied. First, a mathematical model of the multi-area interconnected power system under aperiodic DoS attacks is established. Then, a switching state observer is designed to estimate the states during the hibernating and active periods of the aperiodic DoS attacks, respectively. To save communication resources, an event-triggered mechanism is introduced into the observer-controller channel. Moreover, based on the state observer, a feedback controller is designed. Finally, the three-area interconnected power system is taken as an example to make a simulation-based verification. The simulation results demonstrate that the proposed control method can restrain the adverse impact of the aperiodic DoS attacks effectively.
