Distributionally Robust Modeling of Demand Response and Its Large-scale Potential Deduction Method
The diversity and dispersion of resources at demand side make it difficult to extend the response model of small-scale demonstration projects to large-scale customer groups. This paper intends to complete the generalized modeling of demand response characteristics and its large-scale potential deduction based on small samples of demand response data. Firstly
the distributionally robust fuzzy set of response random parameters is constructed. Secondly
based on the principal component analysis method
the relationship between the power consumption of small sample users and inflection point of dead zone and saturation zone of their response is mined. The combination of commonness and individuality is used to obtain the key parameters of general user response in the process of large-scale generalization
and finally the deduction of large-scale demand response potential based on the small sample data is realized. Numerical examples show that the proposed quantification method of the demand response potential fully considers the randomness of user response
and better describes the common characteristics of the industry and the individual characteristics of users. On one hand
the research results can support the accurate modeling of demand response characteristics of small sample users within the scope of the demonstration project. On the other hand
it can support the deduction and evaluation of response ability of large-scale customer groups in future scenarios.
