Aiming at power system security threats such as failures and external attacks, power system security simulation technologies study system behaviors through simulation experiments or numerical calculation. As information technologies such as automatic control, network communication, and artificial intelligence are widely used, power system has developed into an cyber-physical system(CPS) which is deeply coupled by physical system and information system.The faults caused by physical damage or network attack are interrelated in the power system and can spread across domains, which result in new security threats. Power system security simulation is facing new challenges. This paper reviews security incidents with significant impact on the power system in the past, and analyzes the requirement and development of power system security simulation technologies from three dimensions, i.e., engineering security, network security, and cyber-physical integrated security. From these dimensions, the representative security simulation testbeds are classified and summarized. Moreover, the challenges and development trends of power system security simulation technologies are explored.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
