摘要
信息物理高度融合是未来智能配电网的发展趋势,主要针对配电网信息物理系统(CPS)可靠性评估关键技术进行综述与展望。从配电网信息空间、物理空间的风险来源挖掘入手,进一步对信息物理相依存下的影响因素进行总结和分析;在此基础上,归纳总结了配电网物理系统、信息系统各自典型的可靠性指标分类方式与具体数学表达以及两者耦合下的可靠性指标构建技术,进而总结了配电网CPS可靠性评估算法与方法的研究进展;从配电网CPS异构数据处理、信息物理关联的建模与仿真、配电网CPS可靠性评估指标与方法、配电网CPS广义攻击与防御机制4个方面进行了展望。
The high integration of physical and cyber system is the development tendency of smart distribution network in the future,so the key technologies of reliability assessment for distribution network CPS(Cyber Physical System) are summarized and prospected. Starting with the excavation of physical and cyber system's risk origins in distribution network,the influence factors are analyzed further,based on which,classification methods and specific mathematical expressions of reliability assessment index for physical and cyber system of distribution network and establish technologies of reliability assessment index for CPS are summarized and then the research progress of reliability assessment algorithms and methods is discussed.Four aspects are prospected for distribution network CPS:heterogeneous data processing,modeling and simulation,reliability assessment index and method,generalized attack and defense mechanisms.
