Problems solved by technology
However, after a sudden change in the set temperature, the aggregated power of the air-conditioning load group will quickly rise after being reduced to the minimum value (power rebound phenomenon), which limits the maximum duration of the air-conditioning load to provide spinning reserve

Embodiment Construction
[0075] Further description will be made below in conjunction with the embodiments and accompanying drawings.
[0076] Such as figure 1 Shown, the inventive method comprises:
[0077] 1) Establish an aggregation model for all the air-conditioning loads that can be dispatched. In the aggregation model: divide all the air-conditioning loads that can be dispatched into multiple groups of air-conditioning loads, and sort them in sequence, and build a single air-conditioning load working model with subordinate The aggregated power P of the air conditioning load group in the state g and the subordinate state vector S of the air-conditioning load group g ; and use the temperature adjustment value vector γ of all air-conditioning loads at the scheduling time Adjust the set temperature of the air-conditioning loads in the air-conditioning load group to provide spinning reserve, using the aggregated power P g Calculate the reserve capacity RC of the air conditioning load group in th...

The invention discloses a grouping sequence scheduling method for an air-conditioning load group to provide rotating reserve. Establish an aggregation model for all air-conditioning loads that can be dispatched, divide all air-conditioning loads into multiple groups of air-conditioning load groups, obtain the aggregate power of the air-conditioning load group with a subordinate state and the subordinate state vector of the air-conditioning load group; use the temperature adjustment value vector Adjust the set temperature of the air-conditioning load at the scheduling time to provide spinning reserve, and use the aggregate power calculation to provide the reserve capacity and rebound capacity of the air-conditioning load group during the spinning reserve process; use the group sequential scheduling method to collaboratively optimize the dispatching time of the air-conditioning load group and within the group The selection of air-conditioning loads enables the air-conditioning load group to provide rated reserve capacity within the rated duration. The invention has strong operability, enables the air-conditioning load group to simultaneously meet the requirements of different rated reserve capacity and rated duration of the system, flexibly participates in the operation of the system, and has great space for popularization and application.
Description
technical field [0001] The invention relates to a group scheduling method for electric loads, in particular to a group sequence scheduling method for air-conditioning load groups to provide spinning reserve. Background technique [0002] The increase in new energy power generation brings more uncertainty and unpredictability to the power generation side of the system, and increases the system's demand for balanced resources on different time scales. In the traditional sense, balance resources are provided through resources on the power generation side, resulting in a huge waste of power generation resources. [0003] In recent years, the development of the smart home market, the promotion of communication systems, and the popularization of smart meters have enabled demand-side resources to respond to system signals and participate in assisting the balance of the power system. Due to the high coverage of air-conditioning in urban residents, the power of air-conditioning load...
