    This digest proposes a cyber-resilient control strategy based on sanity authentication in a hybrid centralized-distributed communication architecture (HCDCA) to resynchronize multiple distributed energy resources (DERs) forming a microgrid after severe disturbances or cyber-physical events. Specifically, a multi-time-scale hierarchical resilient control scheme is developed where each DER is equipped with a local agent (LA) for optimal coordination with adjacent LAs. Instead of sharing decentralized measurements only, LAs formulate a vector of measurements to share with the master agent (MA), which coordinates directly with the supervisory controller (SC). Moreover, a convolution-based consensus algorithm (CBCA) is proposed at the MA and SC layers that detects, localizes, and mitigates the impact of any cyber intrusion in the communication link. Furthermore, an algorithm is developed to dynamically decide the master DER. The proposed scheme is tested on a MATLAB Simulink and a small-scale experimental testbed comprising two parallel DERs.
