Due to the increasing concerns about the environmental and economic issues of traditional ships, all-electric ships with energy storage and renewable energy integration have become more and more appealing for the forthcoming future. In this paper, an optimal energy storage system (ESS) capacity determination method for a marine ferry ship is proposed; this ship has diesel generators and PV panels. ESSs sizing optimization and power system scheduling optimization are simultaneously conducted and it is converted to a mixed-integer quadratic programming (MIQP) model with special modeling techniques. The case study shows that the proposed method is flexible and effective, and the relationships between the ESSs size and the discharge rate, life cycle times, or initial investment cost are investigated.

考虑能量管理优化的舰船动力系统电池储能系统优化选型

由于对传统船舶的环境和经济问题的日益关注，具有储能和可再生能源集成的全电动船舶对即将到来的未来越来越有吸引力。本文提出了一种海上渡轮最佳储能系统（ESS）容量确定方法；这艘船有柴油发电机和光伏电池板。ESS 选型优化和电力系统调度优化同时进行，并通过特殊建模技术转换为混合整数二次规划 (MIQP) 模型。案例研究表明，所提出的方法灵活有效，并且研究了 ESS 尺寸与放电率、生命周期时间或初始投资成本之间的关系。
