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.
