如何分配混合动力电动船舶中柴油发电机组与燃料电池之间的能量，对提高船舶经济性和减少能耗至关重要。为了解决这个问题，提出用动态规划方法优化两种动力源的输出功率。首先建立船舶组件的数学模型。然后，基于贝尔曼最优化原理，以最小燃油消耗为目标函数得到柴油发电机组的最优控制序列。仿真结果表明，与开关式控制策略相比，动态规划算法可以合理分配输出功率，使电池SOC保持稳定，有效降低船舶的耗油量。

How to distribute the energy between the diesel generator and the fuel cell of the hybrid electric ship is very important to improve the economy of ships and to reduce energy consumption. To solve this problem, it is put forward that the output power from the two different sources is optimized by using the dynamic programming (DP) algorithm. Firstly, the mathematical model of the ship is established. And then, based on Bellman's principle of optimality,taking the function of minimum fuel consumption as objective, the optimal control sequence of the diesel generator is obtained. The results show that, compared with the switch control strategy, the DP algorithm can distribute the energy reasonably, the battery SOC remains stable, and the fuel consumption of the ship reduces effectively.
