Cluster processing method and device

Abstract

The invention discloses a cluster processing method and a cluster processing device, which are used for dividing a cluster convenient for controlling the voltage of a power distribution network. The cluster processing method provided by the embodiment of the invention comprises the following steps: determining the sensitivity between any two nodes of the power distribution network, the sensitivityrepresenting the degree of influence on the voltage amplitude of the other node of the two nodes when the injection power of one node of the two nodes is increased or decreased by a unit quantity; determining the electrical distance between the two nodes by using the sensitivity, wherein the electrical distance and the sensitivity are inversely proportional, and the smaller the electrical distance between the two nodes is, the higher the feasible degree of the two nodes classified into the same cluster is; and according to the electrical distance, dividing nodes of the power distribution network to obtain a plurality of clusters. The division of the cluster is based on the electrical distance, and the determination of the electrical distance is based on the sensitivity, and the sensitivity is related to the power of the node and the voltage of the node, so that the divided cluster is related to the voltage of the node, and the voltage of the power distribution network can be conveniently controlled by controlling the cluster.

Description

technical field [0001] The invention relates to the technical field of power grids, in particular to a cluster processing method and device. Background technique [0002] A distribution network has many nodes, such as load nodes, distributed energy nodes, and the like. [0003] In order to facilitate the management of the nodes of the distribution network, it is necessary to divide the nodes of the distribution network to divide into multiple clusters, and then manage the nodes of the distribution network in units of clusters. [0004] In terms of cluster division, the prior art mostly uses geographic location, network topology, etc. for division, and the division result will not facilitate the control of the voltage of the distribution network. Contents of the invention [0005] The purpose of the present invention is to provide a cluster processing method and device for dividing clusters that are convenient for controlling the voltage of a distribution network.
