Embodiment 1

[0055] like figure 1 As shown in the figure, the load-side resources are aggregated into an adjustable load virtual unit, and the adjustment process of the virtual unit is realized by the load aggregator controlling a single load-side resource, and finally responds to the power grid peak regulation control demand.

[0056] A load-side resource participating in the main station AGC peak regulation control method of the present invention, the main steps of which include:

[0057] Step 1) The load-side resources aggregated by the load aggregator are equivalent to an adjustable load virtual unit, and the adjustable load virtual unit is to use the intermediate aggregator, use the switch or continuously adjust the output power of the load, so as to respond to the grid's output power. The control target is used to realize that the load-side resources with small capacity and large quantity participate in the automatic control of grid AGC power.

[0058] Step 2) In the provincial powe...

Embodiment 2

[0092] A load-side resource participation master station AGC peak-shaving control system of the present invention includes:

[0093] The data acquisition module is used to convert the load-side resources aggregated by the load aggregator into an adjustable load virtual unit, and obtain the adjustment characteristics of the adjustable load virtual unit, the power grid regulation demand and the power grid peak regulation plan;

[0094] The peak shaving mode determination module is used to determine the corresponding peak shaving mode based on the grid regulation demand of the adjustable load virtual unit;

[0095] The control target calculation module is used to calculate the corresponding control target of the adjustable load virtual unit in each peak regulation mode based on the regulation characteristics of the adjustable load virtual unit and the peak regulation plan of the power grid;

[0096] The control strategy determination module is used to determine the corresponding ...

Abstract

The invention discloses a method and system for load-side resources participating in the AGC peak regulation control of the main station, which aggregates the load-side resources and is equivalent to a load-side resource virtual unit; based on the adjustment characteristics of the adjustable load virtual unit and the peak shaving plan of the power grid, calculate the corresponding control target of the adjustable load virtual unit in each peak shaving mode; based on the change trend of the control target at the next peak shaving control target point , determine the corresponding control strategy; based on the obtained control strategy, the control target is delivered to the load aggregator in real time, and the load aggregator controls each load-side resource under the aggregation according to the control target. The invention realizes that the load-side resource aggregation participates in the power grid peak regulation control as a whole, expands the power grid peak regulation resources, and improves the frequency control quality of the power grid.

Description

technical field [0001] The invention belongs to the technical field of frequency control of electric power systems, and in particular relates to a control method for load-side resources participating in AGC peak regulation of the main station, and also relates to a control system for load-side resources to participate in the AGC peak regulation of the main station. Background technique [0002] With the large-scale connection of new energy sources to the power grid, traditional thermal power sources are replaced on a large scale, resulting in a continuous reduction of the traditional moment of inertia of the power grid, a gradual weakening of the traditional primary frequency regulation capability of the power grid, and a gradual increase in the risk of grid frequency stability. With the development of "source-network-load-storage" interactive technology and the popularization and use of intelligent terminals, load-side regulation resources have become new frequency regulatio...
