Demand response benefit and potential evaluation method based on electricity price

Abstract

The invention discloses a demand response benefit and potential evaluation method based on electricity price. The method includes the following steps: determining the number of users participating in a demand response project based on the electricity price after m years according to the set user growth rate alpha and the intelligent electricity meter implementation progress beta; calculating electric quantity of each user in unit time one day at the new electricity price according to a user response characteristic model; calculating the average electric quantity at ordinary time of the user at the new electricity price according to the daily electric quantity of the user; predicting the number of the users participating the project from the reference year and evaluating the requirement response benefit and potential of a power plant, a power grid, the users and the environment according to the user response degree. By means of the evaluation, the benefit and the demand response potential of the benefited parties are carefully analyzed after the demand response project based on the electricity price is implemented, the benefit evaluation value is quantized, and the method provides reference for planning and cost recovery of the demand response project, helps the government to make decisions, is favorable for well development of the demand response project in the country, and achieves good social benefit.

Description

technical field [0001] The invention belongs to the field of power demand side management, in particular to a demand response benefit and potential evaluation method based on electricity price. Background technique [0002] Demand response is the supply side of the power grid that provides price or incentive signals to urge power users to change their electricity consumption patterns, guide users to use less electricity during peak hours, and use more electricity during low valleys, improve power supply efficiency, optimize electricity usage patterns, and achieve energy conservation and environmental protection. long-term purpose. Demand response is divided into price-based demand response and incentive-based demand response. Price-based demand response means that users respond to changes in retail electricity prices and adjust electricity demand accordingly; incentive-based demand response means that demand response implementing agencies formulate deterministic or time-var...

Problems solved by technology

[0006] In view of the defect that the existing demand response comprehensive benefit evaluation method cannot perform benefit evaluation and potential analysis in advance, the technical problem mainly solved by the present invention is: to provide a method for estimating the implementation benefit and potential of demand response project planning based on electricity price , Fully consider the dynamic changes of the project
