A Location Model for Charging Station and Capacity Considering the Transfer Cost of Power Supply Hub
The current state of development of electric vehicles and their supporting facilities is constrained by the limited layout formed in the early years,and the contradiction between the growing market of electric vehicles and the demand for charging.The construction and operation of charging stations can gain great benefits from the development of charging facilities with great potentials.Considering these factors,taking profit maximizing of charging station owner as the target,a siting and sizing model is constructed.By weighing the costs of power supply hubs,charging stations and charging piles,and the income from satisfying charging demand,the results can be obtained from optimization by utilizing genetic algorithm.It is found that the radius of coverage of charging stations has a large and complex impact on profits and decision result,and it is necessary to conduct market research on many factors affecting the coverage in the pre-investment period of charging station construction.On the other hand,the unit cost of laying electricity has an obvious impact on the decision-making results,and the relatively high cost of laying electricity inhibits the number of charging stations and their capacity,which in turn reduces the profits.Therefore,in order to avoid large deviation in decision result,the two kind of cost should be analyzed at the beginning of the work.
