【摘要】：该文提出了配电系统安全域(distribution system security region,DSSR)体积的概念与算法,分析了DSSR体积对电网的意义。首先,对DSSR体积进行了定义,DSSR描述了配电系统满足N-1安全的运行范围,体积是DSSR大小的度量。其次,提出了DSSR高效运行区的体积定义。再次,提出了基于蒙特卡罗仿真的DSSR体积算法。最后,通过算例验证了体积算法,并进一步研究了体积的用途。DSSR体积能提供一些最大供电能力(total supply capacity,TSC)无法给出的重要信息,选取TSC相同但DSSR体积不同的电网比较,发现体积大的电网具有更好的安全性能,在各个负荷增长方向上的安全裕量更均衡。该文提出的DSSR体积是反映配电网安全性能的新指标,对未来配电网的规划和运行具有重要的应用价值。
[Abstract]:In this paper, the concept and algorithm of (distribution system security region,DSSR volume in safe domain of distribution system are proposed, and the significance of DSSR volume to power network is analyzed. First, the DSSR volume is defined, and DSSR describes the range of distribution system that meets the N-1 security. The volume is a measure of the DSSR size. Secondly, the volume definition of DSSR efficient operation area is proposed. Thirdly, DSSR volume algorithm based on Monte Carlo simulation is proposed. Finally, the volume algorithm is verified by an example, and the use of volume is further studied. DSSR volume can provide some important information that can not be given by (total supply capacity,TSC (maximum power supply capacity). The power grid with the same TSC but different DSSR volume is selected to compare. It is found that the large power grid has better safety performance and more balanced safety margin in each direction of load growth. The volume of DSSR proposed in this paper is a new index to reflect the security performance of distribution network and has important application value for the planning and operation of distribution network in the future.
