Problems solved by technology

However, the traditional center of gravity site selection method has a slow convergence speed in the iterative process, and if the obtained coordinate point is close to a station, it is prone to sudden changes, which affects the convergence speed and the determination of the optimal value.

Embodiment Construction

[0034] A method for selecting a site for an electric bus charging station based on the center of gravity theory, the method comprising the following steps:

[0035] Step 1: Collect basic relevant information. The step of collecting basic relevant information can provide data support for subsequent steps. Among them, the following information is specifically collected: the location coordinates (x i ,y i ); the number m of electric buses that need to be charged at the proposed charging station in the i-th bus station i ;Priority f of the i-th bus station i , f i The main purpose is to ensure that the charging station is as close as possible to some important bus stations, and priority can be given to ensure the normal operation of important stations. In actual use, other variable factors can also be adjusted by f i accomplish.

[0036]Step 2: Initialize, determine the initial position coordinates of the charging station to be selected, and the coordinate values ​​are calcu...

Abstract

The invention discloses an electric bus charging station location selection method based on the center of gravity theory. The method includes the steps of: 1, collecting basic relevant information; 2,initializing to determine the initial position coordinates of the charging station to be selected; 3, determining the distance di(k-1) between the charging station obtained in the (k-1)th iteration and other bus stations and eliminating the disturbance caused by too small distance; 4, updating the position of the proposed charging station; 5, performing convergence checking, and judging whether an optimal location scheme has been obtained, namely, determining that optimal position of the charging station, and stopping calculation if the judging condition is reached. The invention can quicklyselect an optimized station as the location method of the charging station of the electric bus in the bus station, the convergence speed is faster, and the anti-jamming performance is better.

Description

Technical field: [0001] The invention relates to an optimal site selection technology for a bus charging station, in particular to a method for selecting a site for an electric bus charging station based on the center of gravity theory. Background technique: [0002] More and more cities have begun to pay attention to the construction and development of public transportation, especially the maturity of electric vehicle technology has injected new power into public transportation. However, due to the low popularity of electric buses and the existence of short boards such as small battery capacity and slow charging of electric vehicles, it needs to be made up from the planning level to meet the operational needs of electric buses. [0003] Generally speaking, there are currently three charging methods for electric buses: fast charging, slow charging at night and battery pack replacement. Among them, the fast charging current is large, the requirements for charging facilities ...
