A Method for Evaluation of Demand Response Effect Targeted at Load Limit

Abstract

The invention discloses a demand response effect evaluation method with load limit as the target, comprising the following steps: step 1, determining the demand response evaluation time; step 2, with load limit as the target, determining three major evaluation sub-targets; step 3. Establish a demand response effect evaluation system based on the load limit as the judgment standard based on whether it is strongly related to the evaluation sub-objective; Step 4: Standardize the important evaluation indicators and auxiliary evaluation indicators to obtain each evaluation index The percentage of , and then use the weight method for unified solution to obtain the evaluation value. The evaluation method proposed by the present invention has comprehensiveness, independence, ease of measurement, flexibility and practicability, and the source of required data is convenient and easy to understand, and it is solved by weight factor method, which is beneficial to engineering application and can be used in demand response / effective It can play a role of “filling in the gaps” in the evaluation of the effects of sequential electricity use or the formulation of demand response subsidy standards.

Description

technical field [0001] The invention relates to a demand response effect evaluation method with load limit as the target, and belongs to the technical field of electricity service. Background technique [0002] Under the dual influence of the contradiction between power supply and demand, the cost of traditional peaking units, and the environment and resource constraints, demand-side resources are becoming a new element of power grid dispatching. Compared with conventional power generation resources, demand response resources have certain advantages in participating in power grid operation control. For example, when conditions permit, demand response resources can quickly respond to scheduling and control instructions, and the capacity of demand response resources after aggregation is adjustable and flexible; At the same time, due to the relatively scattered distribution of demand response resources, they can be optimized and aggregated from the network and geographical leve...

[0004] A demand response effect evaluation method with load limit as the target. From the perspective of the power grid, a unified and comprehensive evaluation of the actual load curve of a user is carried out in comparison with the load limit target. This type of evaluation method is simple in calculation and applicable Strong and easy to promote, the results directly affect the interests of the power grid and users, and even affect the future development of demand response

At present, there are few studies on demand response effect evaluation methods, focusing on benefit evaluation, lack of target load-oriented demand response effect evaluation research, and building a demand response effect evaluation system with load limit as the target has become an urgent need for large-scale application of demand response.
