Cyber—Physical Power System (CPPS): A review on measures and optimization methods of system resilience

Abstract The Cyber—Physical Power System (CPPS) is one of the most critical infrastructure systems in a country because stable and secure power supply key foundation for national social development. In recent years, resilience has become major topic preventing mitigating risks caused by large-scale blackouts CPPSs. Accordingly, concept significance CPPS are at first explained from engineering perspective this study. Then, review representative quantitative assessment measures applied existing literature provided. On basis these measures, optimization methods reviewed three perspectives, which mainly focused on current research, namely, optimizing recovery sequence components, identifying protecting nodes, enhancing coupling patterns between physical cyber networks. advances modeling cascading failures within CPPS, theoretical research CPPSs, also presented. Lastly, challenges future directions CPPSs discussed.
