Embodiment Construction

[0035] Embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0036] A black-start power supply site selection method suitable for power system partition recovery mode, such as figure 1 shown, including the following steps:

[0037] Step 1: Input the grid structure, unit information and load data of the regional power grid to form a network topology matrix.

[0038] Step 2: Use the discrete particle swarm algorithm to generate an initial scheme for the location of the black start power supply.

[0039] According to the rules of discrete particle swarms, the format of each particle in the initial scheme of black start power supply site selection is as follows, in which each dimension data of each particle represents the state of the node, 0 means that the node does not have a black start power supply, and 1 means The node is set to black start power.

Abstract

The invention relates to a black start power supply location selection method suitable for an electric power system partition recovery mode, which has the technical features of forming a network topology matrix, and adopting a discrete particle swarm optimization algorithm to generate an initial scheme of black start power supply location selection; adopting a continuous particle swarm optimization algorithm to generate an initial scheme of unit partitioning and sorting; adopting the Dijkstra shortest path algorithm to calculate the unit capacity recovery speed of the initial scheme; according to the particle change rule of the continuous particle swarm optimization algorithm, generating a new scheme of unit partitioning and sorting; calculating the weighted sum of the power construction cost of the black start power supply location selection scheme and the unit capacity recovery speed as an evaluation value; and according to the particle change rule of the discrete particle swarm optimization algorithm, generating a new scheme of black start power supply location selection. The method solves the planning problem of selecting the location of the black start power supply, proactively prevents blackouts from the electric power system planning and design level, and improves the recovery efficiency of the electric power system after the blackouts.

Description

technical field [0001] The invention belongs to the technical field of power system operation and control, in particular to a black-start power supply site selection method suitable for the partition recovery mode of the power system. Background technique [0002] With the frequent occurrence of extreme natural disasters and the development of malicious network attacks, modern power systems still have the risk of large-scale power outages. The recovery process after a large-scale power outage is a systematic project. Existing recovery methods are mainly aimed at the passive response of the system after a blackout, and there are few active defenses against blackouts from the planning and design level of the system. If the number and location of black-start power supplies can be reasonably set from the beginning of system planning and design, it can effectively help the power system flexibly respond to major blackouts and shorten the system outage time. Limited by the charac...
