Embodiment Construction

[0042] The present invention will be further described below in combination with specific embodiments.

[0043] Assume that the substation network within the jurisdiction of a certain distribution center Z is as follows: figure 1 As shown, and assuming that the planning is already in the stage of commercial operation, take α=ω=0.5. Among them, A, B, C, D, and E are five locations with different electric vehicle ownership and different road connection conditions. Different road locations have different travel times due to differences in carrying capacity, traffic conditions, and length of road sections. Assuming that the driver always chooses the shortest path when driving between the starting point and the destination, and the battery replacement time of each electric vehicle is 5 minutes, the maximum time for the driver to change the battery is 20 minutes, that is, the time window is [0, 20min] . The node data of the power station network are shown in Table 1.

Abstract

The invention relates to an electromobile power exchanging station site selection method, which is used for selecting sites for an electromobile power exchanging station and solves the problems of difficulty in site selection and planning of the electromobile power exchanging station. The power exchanging station site selection method gives consideration to both benefit of power station operating companies and power exchangers, leads the minimum total cost of the power station operating companies and the power exchangers to be the target function, considers traffic convenience, timeliness and power exchanging station total capacity constraint, adds constraint of hard time windows on power exchanger travelling and power exchanging total time, and selects sites for the electromobile power exchanging station. The method considers different considerations of benefit of both sides in different planning stages with the minimum total cost of the power station operating companies and the power exchangers as the target function, and selects sites for the electromobile power exchanging station in different planning stages by changing benefit weight of the power station operating companies and the power exchangers. The constraint of the hard time windows includes traveling time of a driver reaching a goal power exchanging station, queuing time and power exchanging time.

Description

technical field [0001] The invention relates to a site selection method for an electric vehicle swap station. Background technique [0002] In the context of economic development transitioning to a low-carbon economy characterized by low energy consumption, low pollution and low emissions, the development of electric vehicles has been valued by various countries. The Chinese government is also vigorously supporting the construction of new energy vehicles and their supporting facilities. [0003] There are two types of energy replenishment modes for electric vehicles: charging type and battery swapping type. The charging method uses charging piles as the main equipment, which are mainly used in home warehouses and charging stations. However, it also has defects such as slow charging speed, concentrated charging time, affecting the normal operation of the power grid, and high fixed investment. The battery replacement method refers to the method of directly replacing the emp...
