Cyber-Physical Coordinated Defense Method Against Malicious Attacks for Security and Stability Control System

The close cyber-physical coupling makes network security problems a major challenge to the safe and stable operation of power systems, and it also provides new potential for the cyber-physical coordinated perception and security defense. Focusing on the security and stability control business, aiming at the network security problems brought by cyber-physical integration, this paper excavates the potential of cyber-physical coordination, puts forward the framework of cyber-physical coordinated defense, and improves the ability of security and stability control systems to defend against malicious attacks. Firstly, the impacts of malicious attacks on power security and stability control systems and power primary systems are analyzed through experiments. On this basis, the cyber-physical coordinated defense system and framework for network security are proposed from the time and spatial dimensions respectively. Combined with the traditional network security technology and security and stability control business logic, the network security identification and protection schemes including device-side and master station-side are proposed respectively, and the network security monitoring and analysis application framework of the security and stability control system is given, so as to improve the ability of the security and stability control system to deal with malicious attacks.
