Resilient Consensus Control Scheme for Distributed Energy Storage Systems in DC Microgrids Against False Data Injection Attacks

This paper investigates the resilient consensus control problems for distributed energy storage (DES) systems in DC microgrids (MGs) with false data injection attacks (FDIAs) in the communication channels. The existing resilient control methods still bear some deficiencies, such as poor performance, limited applicability, and heavy calculation. To overcome these problems and to realize the resilient control of bus voltage regulation and state of charge (SoC) balancing for DES systems in DC MG, this article has proposed a resilient consensus control scheme to guarantee resilience under unbounded FDIAs. The proposed scheme uses input-output feedback linearization to construct a second-order linear system for each DES node and utilizes the dual-layer communication architecture to establish the resilient observer. Compared with other model-based resilient control methods, the proposed scheme can effectively deal with unbounded FDIAs with lower costs in both communication and calculation. Then, the stability analysis based on the Lyapunov technique is given to prove the feasibility of the proposed scheme. Finally, the DC MG test model is built in MATLAB/Simulink to verify the efficiency of the proposed scheme.
