Design and Reinforcement Security on Smart Grids Against Cyber-physical Attack (NSoE)

Smart grid is a well-known cyber-physical system. However, its complex nature introduces a new level of security vulnerabilities that reveals urgent needs of security reinforcement against malicious attacks. In this research project, to improve the security level of smart grid, a new security reinforcement process is proposed with three stages; namely (1) Design, (2) Monitoring, and (3) Operation, involved with the aspects of prevention, protection, detection, and control mechanisms. Specifically, we study three tasks with particular emphasis on defense-in-depth though novel techniques. To this end, first, an intelligent method is proposed to evaluate the vulnerable points and the corresponding impact of smart grid subject to various attack strategies. Then, a robust detection framework is developed that leverages the correlation between abnormal/attack incidents and normal signals/states in both the cyber and physical domains. Finally, a game-changing approach based control mechanism is proposed with fully distributed, high secure, and robust characteristics.
