Problems solved by technology

[0003] At present, the classical queuing theory can only estimate the average value of the queue length, queue length and waiting time in the queuing index, and there is no literature that proposes a clear queuing algorithm suitable for expressway electric vehicle fast charging stations to calculate the decision variables of fast charging stations , including the team leader, queue length, waiting time, and charging load of electric vehicles

Embodiment Construction

[0035] A expressway fast charging station queuing algorithm for electric vehicle fast charging stations applied to the expressway fast charging station satisfies the following rules: ① A freeway fast charging station is equipped with several fast charging piles of the same type, which are the same for electric vehicle users ②The rule that fast charging stations provide charging services for electric vehicle users is "first come, first served"; ③Charging stations provide users with parallel services of multiple charging piles; ④There are two types of parking spaces in expressway fast charging stations, one The charging pile is configured to provide charging service and parking service at the same time, and the other only provides parking service. If the user enters the station and needs to wait, the user first stops at the parking space that only provides parking services and waits. When there are free charging piles, the user will receive the charging service at the parking spa...

Abstract

The invention discloses a highway electric vehicle quick charging station queuing algorithm. According to the algorithm, historical traffic flow data of vehicles on a highway are counted and fitted to obtain time records of electric vehicles at highway entrances on a typical day; charging threshold values of electric vehicle users are obtained according to a distance between every two adjacent charging stations on the highway, charging will and residual electric quantity of the vehicles; on the basis of analysis of charging station running characteristics and a classic queuing model, an index system of a quick charging station queuing model is established, and a method for calculating a queue length of each electric vehicle quick charging station, a queuing length, a vehicle waiting time and a charging station load is provided; combining the time records of all of the vehicles at the entrances, the charging time and the waiting time, an effectively charging time interval of each vehicle can be determined, so that the charging loads of each charging station at different time windows can be obtained. Through adoption of the method, dynamic simulation of running states of the highway electric vehicle quick charging stations can be realized.

Description

technical field [0001] The invention relates to a queuing algorithm for expressway electric vehicle fast charging stations. Background technique [0002] With the long-distance driving of electric vehicles on the expressway and the construction of corresponding charging facilities, many problems of electric vehicle charging on the expressway have attracted more and more attention, and the operation simulation of expressway fast charging stations has become an important research topic . If a queuing algorithm for expressway fast charging stations can be proposed to calculate the vehicle captain, queuing length, waiting time and charging load of fast charging stations at different times, based on these decision variables, on the one hand, a satisfactory charging strategy can be formulated for electric vehicles, on the other hand. On the one hand, combined with the power supply capacity of the grid, a reasonable operation plan can be formulated for the fast charging station. ...
