Distributed Control of Multiarea Power Systems with Virtual Power Plants under DoS Attack and Actuator Failure

This paper addresses the distributed control problem of multi-area power systems integrated with virtual power plants (VPPs) under the coexistence scenario of denial-of-service (DoS) attack and actuator failure. To ensure the operational performance of multi-area power systems subject to such attack and actuator failure, a distributed control strategy integrated with load frequency control (LFC) is proposed. Based on Lyapunov stability theory, sufficient conditions for the bounded stability of multi-area power systems are derived. Furthermore, the controller gain parameters are solved by using the linear matrix inequality (LMI) approach. Finally, the effectiveness of the proposed theoretical method is verified through a case study on a two-area power system.
