Abstract
Due to the importance of reliability and security in dc microgrids, it is essential to provide maximum resilience against cyberattacks. However, insufficient global information in the microgrid makes it difficult to accurately identify the location of these attacks. To address these issues, this article develops a novel resilient distributed control mechanism, which ensures average voltage regulation and proportional load sharing in dc microgrids under unknown cyberattacks. The proposed resilient control design does not require any information regarding the nature or location of the attacks. By virtue of a graph theoretical approach and a Lyapunov-based framework, the proposed resilient distributed control strategy is designed in a way such that the system stability is always guaranteed following a comprehensive design mechanism. Finally, the robustness of the proposed resilient distributed control approach is demonstrated via simulations and validated by experimental results.
