Security based Resilient Distributed Energy Management Against DoS and FDI Coordinated Attacks

Denial-of-service (DoS) and false data injection (FDI) attacks pose significant threats to cyber-physical systems. This fact is also true for energy management in smart grids. In this paper, a resilient security energy management strategy is designed to address the synergistic attacks of DoS and FDI that occur in smart grids. The resilient policy references ACKnowledgement (ACK) to identify DoS attacks, sets up trusted nodes to filter anomalous nodes, and finally designs an anti-attack strategy to mitigate the impact of the attacks. Simulation results show that the proposed distributed algorithm can effectively filter out anomalous information and ensure the convergence capability of energy management against malicious data attacks by adversarial agents.
