Abstract
本发明公开了一种考虑电池老化的船舶混合动力能量管理方法及系统，包括：选取电池SOC作为状态变量，选取电机转矩，柴油发电机的功率作为控制变量，通过等效电路电池模型建立电池SOC的状态转移模型；对所述控制变量和所述状态变量进行离散处理；建立考虑电池寿命的代价函数；考虑动力系统动态规划，增加约束条件。能有效平衡混合动力船舶的油耗、排放与电池老化之间的关系，实现长期运营成本的降低。减少了因电池更换所带来的经济负担和维护成本，通过精细的动态规划，它还提高了能量利用的效率，并增强了动力系统的可靠性。本发明为船舶动力系统设计提供了一个更为环保的解决方案，有助于推动海上运输业的可持续发展。
