Calculation method of openable capacity of distribution network based on multi-connection feeder switch optimization

Abstract

The invention discloses a calculating method of open capacity of a distribution network based on multi-interconnecting feeder switch optimization. The method comprises the steps of ranking feeders according to the amount of the interconnection switches, closing all interconnection switches and generating a connected tree according to a topological rule, combining the connected tree and generatinga connected subgraph according to a connection rule, reconstructing the switches in the connected subgraph according to a reconstruction rule, and calculating the open capacity of the feeders in the connected subgraph. The method provided by the invention is connected by the power distribution network and effectively expands the open capacity on the premise of ensuring power distribution reliability; and, the power distribution network frame sufficiently plays a role of enlarging and supporting the open capacity.

Description

technical field [0001] The invention relates to a method for calculating the openable capacity of a distribution network, in particular to a calculation method for the openable capacity of a distribution network based on multi-connection feeder switch optimization. Background technique [0002] Accurately grasping the openable capacity of feeders is of great significance for power supply companies to improve the efficiency of business expansion and installation, reduce the load rate of lines during peak power consumption, and make full use of the carrying capacity of existing equipment. The existing openable capacity calculation method is relatively simple. The main basis is that the calculated openable capacity is relatively conservative based on a given network frame and a specific method. When the method changes, the provided openable capacity can no longer reflect The actual situation of the openable capacity of the power grid cannot give full play to the supporting and ...
