The invention provides a multi-energy energy management system for a diesel-electric hybrid power ship, and the system is characterized in that a data processing unit employs a model prediction control algorithm to calculate the load demand power after a certain period of time according to parameters and historical data collected by a data collection unit; a dynamic programming algorithm is adopted to solve a power generation side optimization combination by taking the load power demand as input, the lowest system fuel consumption as a target function and the safe operation of the system as aconstraint condition, and the start-stop and output power of a diesel generator set and a super-capacitor energy storage unit is regulated and controlled by taking the certain time as a period. By utilizing the working characteristics of peak clipping and valley filling of the super-capacitor, the input and output power of the diesel generator set and the super-capacitor energy storage unit is coordinated through the energy management system and the control strategy thereof, so that emission of a diesel engine is reduced, the fuel efficiency is improved, and the purpose of saving energy is achieved.

    本发明提供一种柴电混合动力船舶多能源能量管理系统,数据处理单元根据数据采集单元采集的参数以及历史数据,采用模型预测控制算法计算一定时间后的负载需求功率;以此负载功率需求为输入、系统燃油消耗最低为目标函数,系统安全运行为约束条件,采用动态规划算法求取发电侧优化组合,以所述的一定时间为周期,对柴油发电机组和超级电容储能单元的启停和输出功率进行调控。本发明利用超级电容削峰填谷的工作特性,通过能量管理系统及其控制策略协调柴油发电机组和超级电容储能单元输入输出功率,以降低柴油机排放和提高燃油效率,达到节约能源的目的。
