Resilient distributed control of islanded microgrids under false data injection attacks

This paper concerns the frequency and voltage restoration problem of islanded microgrids under false data in-jection attacks. A resilient distributed frequency and voltage control protocol is proposed to mitigate bounded false data injection attacks, where an interaction network framework between the original communication network and the hidden network is developed. By using graph theory and a Lyapunov direct method, it is proved that the frequency and voltage of distributed generators can converge to a bounded and acceptable range whether the attacks occur on only the original communication network or both the original communication network and the hidden network. An islanded microgrid system is established in MATLAB/SIMULINK, and several scenario simulations are performed to verify the effectiveness of the proposed method.
