摘要
En 中文
Distributed control strategy has been widely applied in dc microgrids for better performance, but it is susceptible to denial-of-service (DoS) attacks, which can render it ineffective and impact system stability. To this end, this article has proposed a secure consensus control for dc microgrids under DoS attacks, which guarantees bus voltage regulation, current sharing for multiple distributed generation units, and the state of charge balance for multiple distributed energy storage units. Besides, a Zeno-free event-triggered aperiodic communication strategy is proposed to relieve the communication burden of the controller. Based on the Lyapunov method, the stability of the whole closed-loop system is rigorously analyzed and a simplified guideline is provided for control parameters selection and tolerable DoS attack evaluation. Finally, a dc microgrid system is built in a hardware-in-the-loop testbed to verify the effectiveness and superiority of the proposed event-triggered secure consensus controller.
