摘要：
A practical method of reconstruction planning in distribution network based on geometrical observation of security boundary is proposed. Two contents of DSSR(Distribution System Security Region) and TSC(Total Supply Capability) curve related to safety boundary theory are introduced. A number of geome-trical observation figures and geometrical observation indexes reflecting the shape and size of DSSR and TSC curve are designed to fully describe the security and efficiency characteristics of a given distribution network. Then, the concrete steps of the reconstruction planning are presented. The expanded IEEE-RBTS-BUS4 case is used to verify the effectiveness of the proposed method. Case results show that the variation in security region and supply capability can be easily discovered before and after reconstruction through the proposed method. The proposed method provides a new observation method and analysis tool for the new distribution network from the perspective of security and efficiency, which is an important supplement to the traditional method of reconstruction planning. © 2021, Electric Power Automation Equipment Press.
