Embodiment 1

[0043] The present invention provides a method for assessing the potential of power user demand response in the Internet environment, including:

[0044] (1) Count the number of visits of user A to the electricity load and electricity price details through the Internet electricity sales platform in the current day;

[0045] (2) Calculate the similarity of the user load curve before and after the electricity price adjustment, and then use the peak-to-valley load change rate to correct it to form the criterion for evaluating the demand response potential. Take the average load of each hour in the user A’s daily average load curve before and after the electricity price adjustment to form the user’s daily load vector, for example: L i =[2,3,4,5,4,6,4,7,5,6,4,3,5,9,5,6,4,3,7,2,1,3,2,1] , L j =[1,2,4,5,4,6,4,7,8,2,4,3,5,6,5,7,4,3,6,2,1,2,2,1] , to calculate the load curve similarity:

[0046] S ( i , ...

Embodiment 2

[0057] Such as figure 2 As shown, the present invention provides a method for evaluating potential demand response of power users in an Internet environment, including:

[0058] (1) Count the number of visits to electricity load and electricity price by electricity users through the Internet electricity sales platform in the current day;

[0059] (2) Calculate the similarity of the user's daily load curve before and after the electricity price adjustment, and then use the peak-to-valley load change rate to correct it to form an evaluation value of the power user's demand response potential;

[0060] (3) Multiple demand response potential evaluation values ​​are obtained through multiple power sample users' calculations, and a power user demand response potential evaluation function is constructed based on multiple demand response potential evaluation values ​​with the number of load visits and the number of electricity price visits as input variables: dr = αF l +βF p ; The...

Embodiment 3

[0081] This embodiment provides a power user credit evaluation method in the Internet environment, including:

[0082] (1) Construct a power user credit evaluation element system under the Internet environment, including static elements and dynamic elements, where static elements include user identity characteristics such as user population, housing area, housing market average price, heating type, etc., and dynamic elements include electricity consumption behavior , demand response, contract performance capabilities, etc.

[0083] (2) Establish the credit scoring model of static elements and the credit scoring model of dynamic elements respectively; the credit scoring model of static elements is as follows: the retailer sets the total score of each static element M1 to 100, and the highest scores of each item are equal, assuming that the user has four items The elements are all filled in truthfully, and the total score is S 1 =100. That is, the scores of each static element...

Abstract

The invention discloses a method for evaluating the demand response potential of electric power users in the Internet environment, which includes the following steps: (1) counting the number of visits to the electricity load and electricity price by the user through the Internet electricity sales platform in the current day; (2) calculating the electricity price adjustment The similarity of the daily average load curve of the front and rear users, and then corrected by the peak-to-valley load change rate, form the evaluation value of the demand response potential of the power user; (3) Through the calculation of multiple user samples, construct the Variable electricity user demand response potential evaluation function. According to the load data and electricity price data viewed in the Internet environment, the invention uses the demand response potential evaluation function to accurately analyze the user's sensitivity to the demand response electricity price, and then provides a basis for the electricity retailer to formulate demand response incentive measures and electricity price strategies.

Description

technical field [0001] The invention relates to the technical field of electric power analysis, in particular to a method for evaluating potential demand response of electric power users under the Internet environment. Background technique [0002] Power demand response is to provide price or other incentive signals on the power grid supply side to prompt power users to change their power consumption patterns, guide users to use less electricity during peak hours, and use more electricity during low valleys, optimize power consumption patterns, and improve power supply efficiency. With the continuous advancement of the national energy Internet strategy and the power system reform policy, the direction of power market reform has become increasingly clear. The future market will realize the diversification of electricity selling entities, take free competition as the core, realize the effective supply and efficient allocation of electric energy resources, and promote the forma...
