Problems solved by technology

However, the contract theory adopted by the smart grid at this stage is mainly researched around the static model, and there are few designs for the dynamic contract mechanism. In the actual grid energy transaction, the residential power load and the power transmission cost during peak hours change with time. , the static contract mechanism appears to be inelastic in smart grid energy transactions

Embodiment Construction

[0041] In order to facilitate those of ordinary skill in the art to understand and implement the present invention, the present invention will be described in further detail below in conjunction with the examples. It should be understood that the implementation examples described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0042] The implementation example environment is the smart grid energy trading market. Among them, electricity consumers (EC) are employers, and small-scale electricity suppliers (SES) are employees, which can provide power supply services. As an active contracting party, EC provides SES with a dynamic contract consisting of a series of contract terms, including its remuneration and the electricity it provides.

[0043] The specific process is as follows:

[0044] (1) SES learns θ 1 value;

[0045] (2) EC provides a long-term contract {π 1 (q 1 ); 2 (q 1 ,q 2 )};

[0046]...

Abstract

The invention belongs to the technical field of energy transaction of a smart power grid and specifically relates to a dynamic incentive contract design method for energy transaction in a smart powergrid. For the characteristics of selfishness of small-scale electricity suppliers and information asymmetry in energy transaction of the smart power grid, the invention provides a dynamic incentive mechanism design method based on a contract theory. The method is characterized by, with characteristics of varied energy transaction demand and environment being considered, and on the basis of established electricity consumer and small-scale electricity supplier models, studying a two-stage dynamic contract incentive model; and under the condition of meeting incentive compatible constraints and participation constraints of the small-scale electricity suppliers, identifying real cost information of the small-scale electricity suppliers to encourage the SES to participate in long-term energy transaction, thereby preventing renegotiation or extra cost due to reselection of transaction objects, and enabling electricity consumers to obtain a maximum expected effect.

Description

technical field [0001] The invention belongs to the technical field of smart grid energy transactions, and in particular relates to a dynamic incentive contract design method for energy transactions in smart grids. Background technique [0002] With the development of smart grids, a large number of private households, as small-scale electricity suppliers (SES), sell their surplus electricity by building small wind power platforms or solar panels. However, due to the selfishness of SES and electricity consumer (EC), both parties hope to maximize their own utility. In view of the above problems, it is necessary to study an effective energy trading incentive mechanism to mobilize the enthusiasm of both parties to participate. In energy transactions, since SES's power generation and transmission costs are its private information, EC cannot guarantee the authenticity of the data. This information asymmetry becomes a problem that must be solved in the design of incentive mechanis...
