Cyberattack Detection for Converter-Based Distributed dc Microgrids: Observer-Based Approaches

DC microgrids are complex systems connecting various renewable energy sources to different types of loads based on distributed networks. However, the strong reliance communication networks makes dc vulnerable intentional cyberattacks. In this article, two typical observer-based approaches presented address attack detection problem for microgrid systems. The disturbance decoupling approach is utilized eliminate influence unknown load conditions and coupling effect between generation units (DGUs) residuals. proposed method easy design has less computational complexity. performance provided scheme validated by a dSPACE-based platform.
