[0053] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0054] For easier understanding, see Figure 1 The present invention provides an embodiment of a method for regulating and controlling adjustable resources of a virtual power plant, comprising:

[0055] Step 101: Calculate the response credit value of the adjustable resources of the virtual power plant participating in the deployment.

[0056] It should be noted that when dispatching power grid resources, the virtual power plant sends demand information to the aggregator, and the aggregator outputs the dispatch plan and sends the dispatch list and the planned response power to the adjustable resources of its agent according to the dispatch plan. The response credit value of the adjustable resources can be expressed by the response credit value. Therefore, in the present invention, it is necessary to calculate the response credit value of the adjustable resources participating in the dispatch. express, The response credit value of the i-th adjustable resource participating in the allocation. The response credit value of the adjustable resource participating in the allocation The initial value of is set to 0. Specifically, the process of calculating the response credit value of the adjustable resources participating in the deployment of the virtual power plant is as follows:

[0057] (1) Obtain the actual response power of the adjustable resource during the last time it participated in scheduling during the power consumption period ;

[0058] (2) Calculate the actual response power Response to plan The first ratio between ,Right now ;

[0059] (3) Determine the first ratio Is it greater than 1? If so, the response credit value of the adjustable resource participating in the allocation Add 1, that is Otherwise, determine the first ratio Is it greater than the first threshold? If it is greater than the first threshold, the response credit value of the adjustable resource participating in the allocation increases by the first threshold times the first ratio, that is, , is the first threshold. If the first ratio If it is not greater than the first threshold, the response credit value of the adjustable resource participating in the allocation is reduced by 1, that is, , the first threshold is greater than 50% and less than 1. In the present invention, the first threshold is 80%.

[0060] Step 102: Calculate the real-time credit score of the aggregator based on the response credit value of the adjustable resources participating in the allocation.

[0061] It should be noted that the initial credit score of the aggregator The response credit value of the agent's adjustable resources participating in the allocation Calculate, the calculation formula is:

[0062]

[0063] in, is the initial credit score of the aggregator, n is the total number of adjustable resources, i is the adjustable resource number, The response credit value of the i-th adjustable resource participating in the allocation.

[0064] Then calculate the total actual response power of the adjustable resources that the aggregator participated in scheduling last time during the power consumption period , that is, the total amount of actual response power of all adjustable resources that the aggregator participated in scheduling during the power consumption period last time.

[0065] Calculate the total actual response power Total planned response power The second ratio between ,Right now .

[0066] Determine the second ratio Is it greater than 1? If so, the real-time credit score of the aggregator Initial credit score Add 1, that is Otherwise, determine the second ratio Is it greater than the second threshold? , if the second ratio Greater than the second threshold , then the real-time credit score of the aggregator Initial credit score Add the second threshold value times the second ratio, that is, , if the second ratio Not greater than the second threshold , then the real-time credit score of the aggregator is reduced by 1, that is, , the second threshold Greater than 50% and less than 1. In the present invention, the first threshold The value is 80%.

[0067] Step 103: According to the real-time credit score of the aggregator, the aggregator is evaluated and classified into high-level aggregators, medium-level aggregators and low-level aggregators.

[0068] It should be noted that, in the present invention, the classification function K of the aggregator rating is first defined according to the real-time credit score of the aggregator, and the classification function K is expressed as:

[0069]

[0070] Among them, K is the classification function of the aggregator rating, d is the type of adjustable resources, a is the number of adjustable resources, m is the total power generation of adjustable resources, q is the total power that can be allocated, Real-time credit for aggregators, The initial credit score of the aggregator.

[0071] Then, the aggregators whose locations are beyond the set area, whose electricity prices are beyond the set threshold, and whose classification function K≤0 are deleted, and the retained aggregators are divided into high-level aggregators, medium-level aggregators, and low-level aggregators according to the value of K. Specifically, after deleting the aggregators whose locations are beyond the set area, whose electricity prices are beyond the set threshold, and whose classification function K≤0 are deleted, the retained aggregators are sorted in descending order according to the value of K, and the aggregators ranked in the top 10% are classified as high-level aggregators, the aggregators ranked in the middle 50% are classified as medium-level aggregators, and the aggregators ranked in the bottom 40% are classified as low-level aggregators.

[0072] Step 104: Configure the corresponding incentive subsidy mechanism and the incentive subsidy mechanism for adjustable resources according to the level of the aggregator, and send an invitation list for participating in the regulation to the aggregator in turn according to the level of the aggregator, so that the aggregator can use the integrated adjustable resources to complete the electricity consumption regulation corresponding to the invitation list.

[0073] It should be noted that a reward mechanism is set up to reward high-level aggregators and medium-level aggregators, and promote medium-level aggregators and low-level aggregators to upgrade to a higher level; at the same time, the adjustable resources of high-level aggregators and medium-level aggregators are rewarded according to the response credit value. Specifically, the incentive subsidy method for aggregators is: the electricity price incentive subsidy for high-level aggregators is 1%, the electricity price incentive subsidy for medium-level aggregators is 0.3%, and the electricity price incentive subsidy for low-level aggregators is 0, that is, low-level aggregators do not set incentive subsidies. The incentive subsidy method for adjustable resources is: configure the reward value J, allocate the reward value J in proportion according to the level of the aggregator, and allocate the incentive subsidy corresponding to the proportion of the reward value J allocated to the aggregator according to the actual proportion of electricity allocated. For example, a reward value J is set, and according to the level of the aggregator, the high-level aggregators, the medium-level aggregators and the low-level aggregators are allocated the reward value J in a ratio of 6:4:0, and the adjustable resources are allocated the incentive subsidy corresponding to the proportion of the reward value J allocated to the aggregator according to the actual proportion of electricity allocated.

[0074] Invitation lists for participating in regulation are sent to aggregators in order of their ranks, i.e., high-ranking aggregators are invited first, followed by medium-ranking aggregators, and finally low-ranking aggregators. Aggregators use integrated adjustable resources to complete power consumption regulation corresponding to the invitation list, which includes power demand information, power time period information, and power location information.

[0075] In one embodiment, after step 104, the method further includes:

[0076] Count the number of defaults of adjustable resources R1 and the number of defaults of aggregators R2;

[0077] When an adjustable resource defaults twice, that is, R1=2, the aggregator to which the adjustable resource belongs issues a warning to the adjustable resource and resets the response credit value of the adjustable resource to zero;

[0078] When an adjustable resource defaults more than three times, that is, R1 ≥ 3, the adjustable resource will be terminated from the aggregator to which it belongs;

[0079] When an aggregator defaults once, that is, R2=1, the virtual power plant sends a warning to the aggregator and reduces the aggregator's real-time credit score by 1;

[0080] When an aggregator defaults twice, that is, R2=2, the virtual power plant will issue a warning to the aggregator, reduce the aggregator's real-time credit score by 2, and classify the aggregator into a low-level aggregator;

[0081] When an aggregator defaults more than three times, that is, R2 ≥ 3, the aggregator will be deleted and will not be considered as an option.

[0082] The adjustable resource control method for a virtual power plant provided by the present invention calculates the real-time credit score of an aggregator according to the response credit value of the adjustable resources participating in the allocation, and evaluates the level of the aggregator according to the real-time credit score of the aggregator, and divides the aggregators into high-level aggregators, medium-level aggregators and low-level aggregators, allocates corresponding incentive subsidies to the aggregators and adjustable resources, and sends invitation lists for participating in the regulation to the aggregators in turn according to the levels of the aggregators, so that the aggregators use the integrated adjustable resources to complete the electricity consumption regulation corresponding to the invitation list, which is conducive to improving the enthusiasm of the aggregators and adjustable resources to participate in the regulation, and solves the technical problem that the enthusiasm of the existing adjustable resources to participate in the regulation is low, which affects the precise regulation of the adjustable resources of the virtual power plant.

It not only grades the credit of the aggregator, but also conducts real-time evaluation of the credit status of the multiple distributed adjustable resources it represents, thereby realizing the allocation of rewards to adjustable resources with higher credit values ​​and improving the enthusiasm and integrity of adjustable resources.
