基于帕累托的全电船舶混合储能系统设计优化

This paper presents a two-stage Pareto-based design optimization procedure for a hybrid energy storage system, intended for a full-electric vessel. The methodology first identifies a Pareto front as the set of all the optimal configurations in terms of capacity of the two storage units that fulfil the operational constraints within a large discrete configuration space. A second stage identifies the optimal configuration on the Pareto front based on a defined cost function. The approach decouples the analysis of the solutions that can fulfil the operational constraints from the optimization and can be very effective in exploring the effect of several alternative cost functions on the optimal solution. The procedure is illustrated with a case of a full-electric tugboat highlighting when a HESS can be beneficial and how the optimal design can be facilitated.
