Abstract
Electric vessels have developed rapidly with the advancement of transportation electrification in recent years. The power battery capacity of large vessels usually reaches several MWhs, in which case battery change technology is more applicable. A vessel charging and battery swapping station has the dual attributes of power utilization and energy storage and can realize Vessel to Grid through charging and discharging facilities. Aiming at the scenarios of interaction between vessel charging and battery swapping stations and the power grid, this paper studied technical requirements of several participants, established an input-output analysis model and analyzed multiple influencing factors. The results show that revenues cannot be increased effectively with the increase of the number of spare batteries alone; the interactive service can achieve a balance of payments when the battery cost is higher than 1.4 ¥/ Wh, and; benefits may not be gained when the battery life is less than 5 years.
Highlights
There are many inland rivers and lakes in China
The promotion of electric vessels is an important part of transportation electrification [1] and the transformation of port shore power facilities is a future trend [2]
The construction of vessel charging and battery swapping stations is a necessary approach to responding to the development of electric vessels
Summary
There are many inland rivers and lakes in China. A large number of traditional vessels have caused serious pollution. Large-capacity spare batteries in charging and battery swapping stations can be used as an energy storage system to provide auxiliary services for the power grid and obtain additional revenues.
