| ABSTRACT |
|
Under the background that electric vehicles cause enormous supply pressure on the grid, the application of
vehicle-to-grid (V2G) technology can effectively alleviate supply pressure and also bring more economic benefits.
Considering conditions for participating in V2G, pure electric logistics fleets have the advantages of stable work end time and
large remaining power. In this paper, the economic benefits of the pure electric logistics fleet participating in V2G and the
influence factors of the V2G profit are studied. Firstly, the travel data of a pure electric logistics fleet in Chengdu, China is
collected. Secondly, the V2G profit model is established to quantify the economic benefits. Then, 4 V2G scenario modes are
proposed based on window duration, window start time, SOC lower limit and discharge price. Finally, the change law and
influence factors of the V2G profit in each V2G scenario mode are studied from the perspective of the discharge revenue,
charge cost and battery loss cost. The results show that the V2G profit increases with the extension of window duration, the
delay of window start time, the decrease of SOC lower limit and the increase of discharge price. The average profit of
logistics fleets ranges from 3.94 RMB/(vehicleday) to 65.54 RMB/(vehicleday). |
