摘　　要：智能配电网态势感知(SASDN)是配电网稳定运行和精准调度的基础,具有广阔的应用前景。然而,SASDN面临通信延时、科学计算耗时、不同子站系统响应时长不一等引起的一系列时滞不确定性问题,无法满足智能配电网精准调度的要求,限制了其应用范围。为此,从技术层面对SASDN的时滞不确定问题进行了分析和阐述。首先,阐述了配电网态势感知以及时滞电力系统的不确定性研究方法;其次,分析了SASDN时滞不确定性产生的机理和影响;最后,构建了SASDN时滞不确定性研究的总体架构,以期为后续研究工作提供借鉴。Situation awareness of smart distribution network(SASDN)is the basis of stable operation and precise scheduling.Distribution network has a broad application prospect.However,SASDN is faced with a series of time-delay uncertainties caused by communication delay,scientific calculation time,and different sub-station system response time,which cannot meet the requirements of accurate scheduling of intelligent distribution network and limits its application scope.For this reason,the time-delay uncertainty of intelligent distribution network situation awareness is analyzed and expounded from the technical level.Firstly,the research status of this problem at home and abroad is introduced.Secondly,the mechanism and influence of time-delay uncertainty of situation awareness in intelligent distribution network are analyzed.Finally,the general framework of the study on the time-delay uncertainty of situation awareness in smart distribution network is constructed to provide reference for the future research.
