以船舶串联式混合动力系统的能量管理策略为研究对象，建立动力系统数学模型，采用实时性好的基于逻辑规则的能量管理策略，提出基于多目标优化算法NSGA-II优化逻辑规则中的逻辑门限值，以降低油耗和碳排放。某内河运输船循环工况的仿真结果表明，比较传统动力系统，采用优化能量管理策略的混合动力系统节油11.09%，减少碳排放4.32%；比较基于经验的逻辑规则，优化的能量管理策略节油1.18%，减少碳排放2.46%。
Taking the energy management strategy of the ship series hybrid system as the research object, the mathematical model of hybrid system is established and the real-time energy management strategy based on logic rules is adopted. To reduce fuel consumption and carbon emissions, a multi-objective optimization algorithm based on NSGA-II is proposed to optimize logic thresholds in the logic rules. The simulation results of the cycle condition of an inland transport ship show that compared with the traditional power system, the hybrid system with optimized energy management strategy saves 11.09% fuel and reduces carbon emissions by 4.32%; compared with experience-based logic rules, the optimized energy management strategy saves fuel by 1.18% and reduces carbon emissions by 4.32%.
