Cyber-Resilient Sliding-Mode Consensus Secondary Control Scheme for Islanded AC Microgrids

In this article, a cyber-resilient consensus-based distributed control scheme is proposed for islanded ac microgrids. Considering the impacts of false data injection (FDI) attacks on conventional consensus algorithms, hybrid solution presented based combination multiobjective sliding-mode and communication link quality observer to provide reliable performance against different types FDIs. Unlike commonly developed observer-based approach aims form complete localized without requirements transmission extra signals in secondary layer. Using method, system reliability will not be impacted by cyber intrusions terms, system's dynamic deteriorated counteracting operation resulted from adaptive observers under other system-transient conditions such as load dynamics, which can even worsened delays. offset compensation enhanced regulation. Integrating with also ensures effective isolation unbounded extreme cyberattacks. former indirect local observers, operates directly monitoring affected rather than only power enhances its detection. The effectiveness validated through real-time model Typhoon HIL-402 simulator well experimental tests.
