| 摘要: |
| 电力CPS中信息失效可能导致严重物理后果，必须准确评估信息失效威胁下的电力CPS安全性，实现电力CPS安全防御。首先阐述电力CPS建模与信息物理交互机理研究思路。之后通过信息失效来源分析、失效跨空间传递过程分析、安全评估指标计算三个环节建立电力CPS安全评估研究框架。最后从信息网结构优化、路由优化、网络安全防御三方面分析总结了信息失效威胁下的电力CPS安全防御方法，并就后续研究给出建议。 |

| Abstract: |
| Cyber failures may cause severe power outages in a Cyber Physical Power System (CPPS). It is of significance to accurately assess the security of CPPS under cyber failure threat and implement a security defense of the system. First, this paper explains the research ideas on CPPS modeling and the cyber-physical interaction mechanism. Then, it establishes the framework of CPPS security assessment based on failure source analysis, failure spreading process analysis, and security metrics calculation. Finally, the CPPS security defense methods against cyber failure threat are summarized from aspects of information network structure optimization, routing optimization and cyber defense strategy, after which future research proposals are made.
