Abstract

Safely completing voyages is vital for all-electric ships (AESs). However, the existing voyage scheduling methods focus on the generation cost and merely consider the impact of the operation state of the shipboard power system on navigation security. Hence, considering power supply capacity constraints (PSCC), this paper establishes a chance-constrained optimal model for the joint generation and voyage scheduling of AESs. Firstly, considering the N-1 criterion, the linear expressions for PSCC of AESs are expressed based on the interconnection topology of shipboard inverters. Secondly, the explicit chance-constrained expressions for PSCC are established based on the Cornish-Fisher series expansion. Thirdly, a coordinated model is established for joint generation and voyage scheduling and solved by dynamic programming. The actual voyage data are used for simulations, and the results demonstrate the effectiveness of the proposed method.

考虑供电能力限制的全电力船舶联合发电和航程调度

安全完成航行对于全电动船舶（AES）至关重要。然而，现有的航行调度方法只关注发电成本，仅考虑船载电力系统的运行状态对航行安全的影响。因此，考虑到供电能力约束（PSCC），本文建立了一个机会约束的 AES 联合发电和航行调度优化模型。首先，考虑到 N-1 准则，根据船上逆变器的互连拓扑，表达了 AES 的 PSCC 线性表达式。其次，基于 Cornish-Fisher 数列展开建立了 PSCC 的显式机会约束表达式。第三，建立联合发电和航程调度的协调模型，并通过动态编程求解。利用实际航程数据进行仿真，结果证明了所提方法的有效性。
