Large-scale charging pile planning model modeling method based on small data

Abstract

The large-scale charging pile planning model modeling method based on the small data comprises: carrying out that charging rule modeling according to small-scale electric vehicle charging behavior characteristic data, and obtaining a data distribution model of each characteristic data; and predicting large-scale charging data by adopting a data distribution model obtained by a Monte Carlo method to obtain to obtain a charging behavior when the electric vehicle is accessed in a large scale; and based on the large-scale charging data predicted by the Monte Carlo method and the model hypothesis,deriving and obtaining an equivalent charging load curve; constructing a regional charging pile planning model for realizing minimum peak-valley difference between charging equipment investment and disordered charging loads; and carrying out optimization solution by combining related constraint conditions and considering other influence factors in a regional charging pile planning model establishment process. By the adoption of the modeling method, large-range charging pile setting can be planned on the basis of existing small-scale data, and the minimum peak-valley difference of equipment investment and disordered charging loads during electric vehicle charging is achieved.
