Abstract

The invention provides a method and device for partitioning a distribution network network, including obtaining the electrical distance between every two load nodes of the distribution network; converting the electrical distance between every two load nodes according to a preset conversion rule For the space weight between every two load nodes, the space weight matrix is ​​obtained according to the space weight between every two load nodes; the fuzzy equivalent matrix of the space weight matrix is ​​obtained; according to the fuzzy equivalent matrix and based on the fuzzy clustering method, the The load nodes of the distribution network are partitioned; thus, in the process of partitioning the distribution network, the electrical distance between the load nodes is converted into a space weight matrix, and the fuzzy equivalent matrix of the space weight matrix is ​​determined. According to the fuzzy equivalent matrix And based on the fuzzy clustering method, the load nodes of the distribution network are partitioned, the data processing process is simple, and the dynamic partition of the distribution network can be realized.

Description

technical field [0001] The present invention relates to the technical field of power systems, and more specifically, to a method and device for partitioning a distribution network. Background technique [0002] China's distribution network is in a stage of rapid development. With the rising demand for electricity and the penetration rate of distributed generation (DG) in the distribution network, the scale of the distribution network is increasing, and the power grids at all levels connection, the network architecture is more complex. The emergence of the distribution network containing DG marks the transformation of the control mode of the distribution network. The distribution network containing DG needs to be able to cope with the access of high penetration DG, and it is necessary to solve the problem of large-scale access of distributed energy in the distribution network. . [0003] At present, the methods for optimizing and partitioning the distribution network includ...
