Detection of Stealthy False Data Injection Attacks in Modular Multilevel Converters
A modular multilevel converter (MMC) in a high-voltage direct-current (HVDC) transmission system consists of an electric-coupled physical system and a communication-coupled cyber system, leading to a cyber-physical system (CPS).Such a CPS is vulnerable to false data injection attacks (FDIA), which are the main category of cyberattacks.FDIAs can be
