Problems solved by technology

[0002] With the development of power grid interconnection and long-distance AC / DC transmission technology, the scale of the power system is expanding day by day, and the power grids at all levels are constantly interconnected, and the reliability and stability of the system operation are also increasing. Due to the increasingly complex environment and the inevitability of various natural disasters, the network structure and dynamic characteristics of the power system are also becoming more complex, the operating conditions are more demanding and difficult to predict, and the risk of large-scale blackouts in the power system still exists
[0003] At present, the black start partition of the power grid is divided according to the location of the black start power supply, the grid structure, the connectivity within the black start partition, the balance of the scale of each partition, and the power balance within the partition, without considering the state of the unit to be restored (hot state and cold state), thus There will be too long waiting time for black boot partition grid connection

Embodiment Construction

[0048] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0049] Such as figure 1 As shown, a black boot partitioning method includes the following steps:

[0050] Step 1. According to the shortest recovery path from the units to be recovered in the hot state to the black start power supplies, distribute the units to be recovered in the hot state to the black start partitions as evenly as possible;

[0051] Step 2. For each black start partition, verify the recovery path of the hot state to be restored units, and adjust the hot state to be restored units that do not meet the preset recovery requirements to other black start partitions or eliminate them;

[0052] Step 3: According to the shortest recovery paths from the cold-state units to be restored...

Abstract

The invention discloses a black-start partitioning method and system, a storage medium and computing equipment, the state of a unit to be restored is considered, the unit to be restored in a hot state is equally distributed to each black-start partition as much as possible, on the premise that the basic requirements of the black-start partitions are met, the power restoration speed of each partition is increased to the maximum extent, and the power restoration efficiency is improved. Recovery time difference of the partitions is reduced, grid-connected waiting time of the black-start partitions is shortened, and power failure loss of a power grid is reduced.

Description

technical field [0001] The invention relates to a black boot partitioning method, system, storage medium and computing equipment, and belongs to the technical field of electric power systems and automation thereof. Background technique [0002] With the development of power grid interconnection and long-distance AC / DC transmission technology, the scale of the power system is expanding day by day, and the power grids at all levels are constantly interconnected, and the reliability and stability of the system operation are also increasing. Due to the increasingly complex environment and the inevitability of various natural disasters, the network structure and dynamic characteristics of the power system are also becoming more complex, the operating conditions are more demanding and difficult to predict, and the risk of large-scale blackouts in the power system still exists. [0003] At present, the black start partition of the power grid is divided according to the location of ...
