As distributed control layer makes dc microgrids vulnerable toward cyber attacks, the identification and mitigation of attacked agent(s) becomes even more challenging with heterogeneity between each source based on factors, such as capacity, reliability, and generation cost. This letter proposes a novel resilient methodology, which involves detection using adaptive discord element and immediate mitigation via an event-driven approach. The proposed approach successfully mitigates cyber attacks under experimental conditions.
