Description
[technical field]
The present invention relates to network load regulation and control field, the acquisition methods of the customer response model particularly under a kind of Peak-valley TOU power price and system.
[background technology]
The mode of the electricity consumption behavior of user is guided by Peak-valley TOU power price, it is the important way of carrying out network load regulation and control, obtain extensive concern in countries in the world at present, and be applied in provinces such as the developed countries such as America and Europe and domestic Guangdong, Jiangsu, Zhejiang.In order to formulate Peak-valley TOU power price better, existing scholar carries out modeling analysis to the respondent behavior of user under Peak-valley TOU power price.Existing method mainly comprises the method for Corpus--based Method principle, the method based on consumer psychology and the method based on Power demand price elasticity coefficient.When applying these methods, general supposition all types of user response model is known, and carries out the Optimal Decision-making of tou power price on this basis.Due to the complicacy of user group, the respondent behavior of user is difficult to carry out accurate description by the parameter of supposition, a kind of more rational method is that the actual measurement load data utilizing Peak-valley TOU power price to implement front and back carries out quantitative analysis to the response parameter of user under different model, but up to the present, relevant this kind of technical research is still fewer.
