Power system security simulation technologies study system behaviors via simulation experiments or numerical calculations to deal with security threats such as system faults and external attacks. With the wide application of information technologies such as automatic control, network communication, and artificial intelligence, the power system has developed into a cyber-physical system(CPS), where the physical and information systems are deeply coupled. Faults caused by physical damage or network attacks are interrelated in the power system and can spread across domains, resulting in new security threats. Therefore, power system security simulation is facing new challenges. This paper reviewed the security incidents that have significantly impacted the power system and analyzed the requirement and development of security simulation technologies for power systems from three dimensions: engineering security, network security, and cyber-physical integrated security. Therefore, the representative security simulation testbeds were classified and summarized. Moreover,the challenges and development trends of the power system security simulation technologies were explored.
