Abstract
Efficient energy management is crucial for sustainable maritime operations, but limited experimental data hinders the shift from rule-based to optimisation-based strategies in practical applications. This study investigates a dual-objective optimisation strategy for energy management in a hydrogen fuel cell-powered ship, aiming to minimise energy consumption and fuel cell operational stress while guiding practical implementation. A scaled experimental platform was developed to simulate real-world and ship operational conditions, incorporating equipment response characteristics, time-delay effects, and environmental noise. The proposed forward dynamic programming strategy was compared with three rule-based strategies through experiments under transient and steady-state conditions, with robustness evaluated via systematic testing. Results show that, compared to conventional shipboard energy management and state-machine strategies, the optimisation approach reduced energy consumption by 8.20% to 18.7%, decreased fuel cell operational stress by up to 98.52%, and demonstrated robustness under complex navigational conditions. The experimental platform validated the performance of energy management strategies, with the scaling method ensuring reliable implementation. This study provides a robust experimental framework and practical guidelines for implementing optimisation-based energy management in ship power systems, bridging the gap between theoretical research and practical application.
