【摘要】 混合动力船舶通过合理配置各动力源容量可有效提高储能系统利用率，提升航运经济性。针对特定船舶典型工况下的实际负载功率曲线，分别利用平均值法和基于频谱分析的低通滤波法求得船舶动力源各参考功率值。在考虑电池全寿命周期成本的基础上，建立以储能系统总成本和总质量最优的双目标函数，确定以储能元件型号与串并联数量为决策变量，在满足系统峰值功率和最大能量等约束条件下，利用第二代非支配排序遗传算法对复合储能系统进行最优容量配置。算例分析的结果验证了复合储能系统多目标优化模型的正确性以及其较纯电池储能在成本和质量方面的优越性。更多还原

【Abstract】 The reference power values of a ship’s power source are defined based on the actual load-power curve at typical working conditions by means of mean value method and low pass filtering method. The objective function for optimizing total cost and total weight of the system is constructed with life cycle cost of the cell integrated. The model and number of storage elements are defined as the decision-variables. The optimal capacity configuration of hybrid storage system is calculated by means of the second-generation non-dominated sorting genetic algorithm under the constraints in peak power requirement and maximum energy requirement.更多还原
