Adaptive Resilience Control of DC Microgrids under Hybrid DoS and FDI Attacks and Communication Delays

Within the domain of DC microgrids, the restoration of DC bus voltage to its nominal value and ensuring equitable current sharing among distributed generation units represent formidable challenges, exacerbated by the presence of denial-of-service (DoS) attacks, false data injection (FDI) attacks, and communication latency issues. To address this issue, an adaptive resilient secondary control strategy is devised in this paper. The findings demonstrate that this technique is capable of counteracting FDI signals during DoS attacks through the introduction of an adaptive compensation term. Consequently, it ensures effective voltage regulation and equitable current sharing under conditions of mixed attacks and communication delays. Furthermore, the stability of the system is rigorously proven through Lyapunov theory. Ultimately, the practicability and effectiveness of the proposed control strategy are conclusively validated via experimental verification.
