Distributed adaptive resilient control for mitigating cyber attacks in DC microgrids

This paper addresses the stability problem of cyber-physical DC microgrids under false data injection (FDI) attacks. A distributed adaptive resilient control method is proposed to ensure that the control objectives of proportional current sharing and average voltage balance are achieved in DC microgrids. The designed control strategy generates an adaptive resilience compensation term based on the residual between the estimate states of a well-designed estimator and the actual states, which does not require all the states of the distributed generations and any information of FDI attacks. The simulations for DC microgrids validate the effectiveness of the proposed method.
