Abstract

The invention discloses a method for quantitatively analyzing the influence of the electric vehicles on an urban power distribution network. The method comprises the steps of S1, obtaining the first data related to the electric vehicles, and obtaining the first prediction data according to the first data; S2, obtaining a charging moment distribution value lambda of the electric vehicles within one day according to the behavior habits of the users using the electric vehicles; S3, obtaining the charging power values Pi of the electric vehicles at different moments according to the lambda and the battery capacity of the electric vehicles; S4, obtaining the second prediction data according to the Pi and the first prediction data; S5, obtaining the total maximum power value P' max of the power distribution network, and obtaining the maximum charging load specific gravity value of the electric vehicles according to the second prediction data and the P' max; S6, obtaining the second data related to the electric vehicles, and obtaining the third prediction data according to the second data; and S7, counting the maximum charging load specific gravity value, the power distribution network capacity value and the third prediction data of the electric vehicles in the current condition level year and a planned level year according to the steps S1 to S6, and analyzing the influence of the electric vehicles on the urban power distribution network according to the counting results.

Description

technical field [0001] The embodiment of the present invention relates to the technical field of electric vehicles, in particular to a method for quantitatively analyzing the impact of electric vehicles on urban power distribution networks. Background technique [0002] The charging of electric vehicles is random and mobile, with large peak and valley differences in charging load and low utilization hours. The disorderly charging of electric vehicles has a profound impact on four aspects: load structure, system peak-to-valley difference, distribution network utilization, charging facilities and supporting grid construction. At present, there is no systematic data-based analysis of the impact of electric vehicles on grid load method of prediction. Contents of the invention [0003] In view of the deficiencies in the prior art, the embodiment of the present invention provides a method for quantitative analysis of the impact of electric vehicles on the urban distribution net...
