Push-Sum-Enabled Resilient Microgrid Control

This letter devises a distributed microgrid control allowing for time-varying networks utilizing a continuous-time push-sum algorithm. The novelty of the push-sum-based approach lies in: 1) the ability to deal with unbalanced cyber network which represents unreliable communication among distributed energy resources (DERs); 2) the capability of switching among communication networks so as to provide non-interrupted operation; and 3) resiliency against cyber attacks. Case studies verify the efficacy of the new distributed microgrid control strategy and its capability of providing communication robustness while ensuring resilient frequency regulation and active power sharing.
