Consensus Check in the Detection of Faulty and Hijacking Attacks for Multiple Converter-based Microgrids

Microgrids are nowadays exposed to cyber-security challenges due to the integration of information and communications technologies (ICT). Cyber-attacks have the potential to critically compromise the infrastructure of microgrids, leading to widespread blackouts and significant interruptions in power supply. To address this problem, a multiple converter-based microgrid is formulated, after which a consensus check-based attack detection method is proposed to detect false data injection attacks in the communication links among distributed generations within microgrids. The proposed detection method is independent on microgrid parameters with less computational burden. Simulation results demonstrate the feasibility and effectiveness of proposed method.
