In the dc microgrid, the dc bus voltage recovery and proper current sharing may be a challenging task under the denial of service (DoS) attacks. To get around this issue, a distributed edge-based event-triggered control (ETC) strategy is proposed in this article. It is shown that the proposed technique could eliminate the dc bus voltage deviation and achieve proper current sharing under the DoS attacks by designing a new sampling and triggered mechanism. As a result, the system can effectively resist the DoS attacks, and the communication burden can be greatly relieved. Besides, the system's stability is proved by the Lyapunov theory, and it demonstrates that the edge-based event detector is able to guarantee the asymptotic stability of the dc microgrid under DoS attacks. Finally, the experimental case studies are presented to verify the feasibility of the proposed control method.
