Embodiment Construction

[0036] The specific embodiments of the present invention will be further specifically described below through specific embodiments in conjunction with the accompanying drawings.

[0037] like figure 1 As shown, the flowchart of the load control method of the present invention includes the following steps:

[0038] (1) Obtain the total amount of load control:

[0039] The total amount of load control is the total amount of regional load shedding calculated by the provincial regulation and control department. By removing the load of the total amount of control in the county-level power supply area under its jurisdiction, the power grid can be restored to safe operation.

[0040] (2) Calculating the load cut-off target amount in each area:

[0041]In order to avoid excessive load shedding in each area under the region, it is often necessary to pre-determine the index ratio of load shedding in each area, and distribute the target load shedding of each area according to the load ...

Abstract

The present invention relates to the field of power grid dispatching control, in particular to a regional power grid optimal load control method considering regional balance, which is characterized in that it includes the following steps: A) obtaining the total amount of load control; B) calculating the target amount of load removal in each area; C) Select the line to be pulled from the pull-limit sequence table; D) Construct the full load shedding model and the short load shedding model; E) Build the regional load balance model; F) Calculate the full load cut off and short load in each area Cut-off and regional load balance value; G) Output the cut-off lines in each region; the region refers to the county-level power supply units and district-level power supply units within the jurisdiction of the regional power grid. The beneficial effects of the present invention are: on the basis of satisfying the shedding load, the total shedding load can be reduced, excessive shedding can be avoided, economy and regional fairness can be effectively taken into account, the load shedding can be reduced to the greatest extent, and the power grid can be fully guaranteed Scheduling fairness.

Description

technical field [0001] The invention relates to the field of power grid dispatching control, in particular to a regional power grid optimal load control method considering regional balance. Background technique [0002] Regional power grids need to adopt emergency load control methods to deal with various situations that may easily lead to line overruns, unbalanced power generation and power supply, and grid frequency drops. In the load control of the existing regional power grid, in order to maintain the important power supply of users, the line is often manually selected from the pull-limit sequence table to cut off. Due to the fluctuation of the load, the cut-off cannot be carried out effectively according to the load cut-off ratio pre-allocated in each area. Accurate resection resulted in excessive and unbalanced load resection in each area. Existing load control technology has a single control target, most of which aim at the minimum removal amount, and the constructed...
