配电系统安全域的体积
Volume of Distribution System Security Region
摘要
Abstract
This paper proposed the definition and algorithm of distribution system security region (DSSR) volume; and illustrated the meaning of DSSR volume for the grid. First, this paper defined the DSSR volume. DSSR describes the region that contains all operating points of distribution system which meet the N-1 security guidelines. Volume is a measure of the DSSR size. Secondly, the concept of efficient operation region volume was proposed. Thirdly, the algorithm of volume based on Monte-Carlo simulation was proposed. Finally, a case study was provided to verify the algorithm of DSSR volume and study the application of DSSR volume. DSSR volume could provide some critical information that the total supply capacity (TSC) cannot give. We compared two distribution networks of which TSC was the same but DSSR volume was different. It is found that the distribution system whose DSSR volume is bigger have a better security performance; and the safety margin of the distribution network is more balanced in all direction. DSSR volume proposed in this paper is a new index to describe the distribution network security performance; it is of vital significance for the future smart distribution network planning and operation.关键词
