| Abstract: |
| A cyber physical system coupling cyber and physical systems makes the power system more controllable and observable, while its failure will cause more serious power safety accidents. How to combine communication factors to analyze the interplay between the cyber and physical systems is a key issue in enhancing the resilience of the cyber physical power system. First, this paper designs the framework of the cyber physical power system, defines the characteristics of the cyber physical power system resilience and analyzes its significance. Second, based on the transmission principle of cyber flow path, this paper introduces the characteristics and development trend of communication technology, and analyzes the impact of different extreme events on resilience according to the characteristics of cyber network. Next, a joint simulation method of cyber physical power system is summarized. Then, the resilience enhancement strategies at each level of the cyber physical power system are summarized. The feasibility of emergency communication technologies such as satellite communication and unmanned aerial vehicle communication are explored. Finally, future challenges of the cyber physical power system resilience research are elaborated. |
