Modeling of Components in Smart Distribution Systems for Real-time Security Analysis
摘要
Abstract
Smart distribution system contains new components such as distributed generation,energy storage system,demand response,microgrid and soft open point.The component models for security analysis are established,and a new security analysis method is also proposed.Firstly,the concept of security service capability(SSC)for distribution system is proposed,which reflects real-time power adjustment capability of the new components on the distribution network side.Secondly,the SSC-based security analysis method is proposed.Thirdly,based on the analysis of component security roles,security service forms and limits,the medium-voltage-side node models with different combinations of various components are constructed.Finally,the component modeling process is demonstrated through a case study,and the correctness of the proposed models and method is verified by the SSC-based security analysis.The proposed models lay a foundation for the security analysis of smart distribution systems,and the SSC provides new key data for the security analysis by system operators.关键词
