Abstract

The invention belongs to the technical field of power system recovery and control and particularly relates to an ant colony algorithm-based dimension reduction type power system net rack reconstruction method. The problem that the optimal searching dimension of a complex large power system with a large number of nodes and circuits is too large during the net rack reconstruction period of the system recovery can be solved. During the net rack reconstruction period of the power system, a trunk circuit is searched on the basis of an ant colony algorithm, and the states of states of one part of circuits in the system are determined. Therefore, the number of circuits with unknown states in the system is reduced. The dimension of the follow-up optimizing problem is reduced. The speed of the optimizing calculation is accelerated, and the optimizing efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of power system recovery and control, and in particular relates to a power system grid reconfiguration method based on an ant colony algorithm to realize dimensionality reduction. Background technique [0002] Grid reconfiguration, as a connecting link in the process of power system restoration control, needs to make full use of the power generation provided by the power generation units that have been restored to the grid at the initial stage of power system restoration, send power to the outage station as quickly as possible, and establish a stable The power grid lays the foundation for the comprehensive recovery of the power system. [0003] Existing research work on power system grid reconfiguration mainly includes optimizing the target grid, optimizing the recovery sequence of non-black-start units, and optimizing the recovery path of non-black-start units. The present invention mainly relates to optimi...
