Maritime transportationis currently responsible for about 90% of the worldwide trade and contributes about 2.7% of the global carbon emission. To establish a sustainable maritime system, transportation electrification is an inevitable trend. Under this context, cold ironing technology for all-electric ships (AESs) emerges. In this paper, we propose a tri-level pricing framework of cold ironing services for AESs, which comprehensively considers the voyage scheduling of AESs, the power system dispatch, and the profit of the cold ironing serving entity (CISE). Time-of-use (TOU)-based pricing, where price level and price structure are jointly optimized, is formulated based on the carbon integrated distribution locational marginal pricing (DLMP). The proposed pricing strategy is verified in a three-seaport system. It is found that compared with the real-time pricing strategy and the flat pricing strategy, the proposed method can better incentivize the AESs to realize power congestion management and emission control. Besides, it guarantees the profit of CISE with low risks and helps the customer to hedge the market risks.

基于碳综合电价的全电动船舶冷烫服务定价策略

海运目前占全球贸易的 90% 左右，贡献了全球约 2.7% 的碳排放。建立可持续的海事体系，交通电气化是必然趋势。在此背景下，全电动船舶（AES）冷熨技术应运而生。在本文中，我们提出了一个AESs冷熨服务的三级定价框架，该框架综合考虑了AESs的航次调度、电力系统调度和冷熨服务实体（CISE）的利润。基于分时电价（TOU）的定价，价格水平和价格结构共同优化，是基于碳综合分布区域边际定价（DLMP）制定的。提议的定价策略在三海港系统中得到验证。发现与实时定价策略和平面定价策略相比，该方法可以更好地激励AES实现电力拥塞管理和排放控制。此外，它以低风险保证了CISE的利润，帮助客户对冲市场风险。
