Problems solved by technology

Among them, the monopoly model is not suitable for distributed renewable energy generation distributed across the grid owned by consumers; the Bertrand model needs to assume that producers in the market have the same marginal cost curve, which is very important for simulating several large utility companies However, it cannot represent distributed renewable generation with different marginal production costs; although the SFE model can predict market behavior, because both the supply function and the cost function must be determined, the computational complexity is very large and cannot satisfy current needs

Embodiment 1

[0055] The following is an introduction to Embodiment 1 of the aggregator collaboration method based on the demand response market provided by this application, see figure 1 , embodiment one includes:

[0056] S11. When the total demand of the resource buyer is fixed, create an inverse demand model to obtain the relationship between demand response contribution and demand response resource price;

[0057] S12. Construct a Coumot model, the Coumot model includes an aggregator cost model and a resource provider cost model;

[0058] S13. Determine the profit model of the aggregator according to the cost model of the aggregator, solve the profit maximization problem of the aggregator in combination with the inverse demand model, and obtain the contribution of each aggregator;

[0059] S14. According to the cost model of the resource provider and the contribution of each aggregator, solve the cost minimization problem of the aggregator, and obtain the purchase cost of each aggrega...

Embodiment 2

[0074] Such as Figure 4 As shown, embodiment two specifically includes:

[0075] Step 1: Calculation of the inverse demand model.

[0076] Under the premise that the sum of demand response contribution and generator power generation is a fixed value, use the optimal power flow algorithm to find the optimal cost of each output power, and obtain the node marginal price (that is, the demand response resource price). A series of points of demand response contribution and LMP value, linear regression by least squares method to obtain an inverse demand model (this model describes the cost of providing electricity at different nodes):

[0077]

[0078] Among them, π is the price per unit of demand response resources, φ is the offset of the inverse demand model, and △L is the amount of demand response resources, indicating the rate of change of price relative to the contribution of demand response.

[0079] Step 2: Establishment of the Coumot model.

[0080] For each aggregator...

Abstract

The invention discloses an aggregator cooperation method based on a demand response market. In a demand response market comprising a resource purchaser, an aggregator and a resource provider, the method provides an aggregator cooperation scheme: determining a cost model and a profit model of the aggregator according to constraint conditions, solving the profit maximization problem and the cost minimization problem of the aggregator, and obtaining a demand response strategy of each aggregator, so that the purposes of fully mining the resources on one side of the resource provider and integrating the demand response resources are achieved, and supply-demand balance of the demand response market is achieved. In addition, the invention further provides an aggregator cooperation device, equipment and system based on the demand response market, and the technical effects correspond to the technical effects of the method.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a demand response market-based aggregator collaboration method, device, equipment and system. Background technique [0002] Demand response (DR) technology can fully tap user-side resources, use users as resource providers, guide users to actively participate in the operation and regulation of the power market, and also play a greater role in promoting the power system's peak-shaving and valley-filling. It is one of the key technologies to promote the construction of ubiquitous power Internet of Things. However, demand response resources are highly dispersed, and their elasticity level often does not meet the requirements of grid demand response. It is difficult to conduct bilateral transactions with resource buyers alone, and the decision-making of a single user cannot meet the management and optimization requirements of demand response. [0003] To quantify cost-ba...
