摘要：
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. © 2023 Automation of Electric Power Systems Press.
