摘要

续航里程有限、运载能力短缺是电动船舶发展受阻的关键原因，海上充电平台是解决这一难题的可行路径。不同于陆地充电站，一方面，海上充电平台选址定容与电动船舶电池配置相互耦合，电池重量影响船舶吃水深度与能耗特性，改变充电需求；另一方面，电池体积影响载货量与航运效益，改变规划目标。因此，需要在规划海上充电平台时协同考虑电动船舶电池容量优化。针对此问题，提出了电动船舶电池容量与海上充电平台选址定容优化规划方法，基于水动力学构建电池重量-推进能耗、电池体积-运载能力解析函数，作为约束引入优化规划模型以提升运载能力；考虑复杂海洋环境下充电平台建设成本以及风光资源差异，优化海上充电平台选址，提高电动船舶经济航程。以上海—香港航线为例，与不考虑耦合情况相比，所提方法可将电动船舶经济航程提升至千公里级，航运综合效益提升45.79%。

Abstract

Limited cruising range and insufficient carrying capability are the key reasons for hindering the development of electric ships

and offshore charging platforms represent a viable solution to this problem. Unlike the land-based charging stations

on one hand

the siting and sizing for offshore charging platforms is coupled with the battery configuration of electric ships

and the battery weight affects the draft depth of ships and energy consumption characteristics

thereby altering charging demand. On the other hand

the battery volume influences cargo capability and shipping efficiency

thus changing the planning objectives. Therefore

it is necessary to collaboratively consider the optimization of battery capacities of electric ships when planning offshore charging platforms. To address this issue

this paper proposes an optimal planning method for battery capacities of electric ships and siting and sizing of offshore charging platforms. Based on hydrodynamics

the analytical functions for the battery weight-propulsion energy consumption and battery volume-carrying capability are constructed and introduced as constraints into an optimal planning model to enhance the carrying capability. Furthermore

by considering the construction costs of charging platforms in complex marine environments and the differences in wind and solar resources

the siting of offshore charging platforms is optimized to improve the economic cruising range of electric ships. Taking the Shanghai-Hong Kong route as a case

compared with the situation without consideration of the coupling

the proposed method increases the economic cruising range of electric ships to thousands of kilometers and improve the comprehensive shipping benefits by 45.79%.
