【摘要】：针对由发电机组和动力电池两种不同的电源组合而成的混合动力船舶供电系统,在功率需求给定的情况下,合理地分配两种电源的功率输出,使得混合动力船舶在整个航行周期内的总耗油量达到最小是能量管理系统需要解决的问题。采用一种动态规划的方法优化两种电源的功率输出比重,通过建立包含动力电池等效油耗的最小油耗量的目标函数得到柴油发电机的最优控制序列,从而计算出整个航行周期内柴油发电机的最小油耗值。仿真结果表明,与开关式控制策略相比,该方法能有效降低混合动力系统的油耗量。
[Abstract]:According to the hybrid ship power supply system which is composed of two different power sources: generator set and power battery, the power output of two kinds of power sources is reasonably distributed under the given power demand. It is necessary to solve the problem of energy management system to minimize the total fuel consumption of hybrid ships in the whole voyage cycle. A dynamic programming method is used to optimize the power output gravity of the two power sources. The optimal control sequence of the diesel generator is obtained by establishing the objective function of the minimum fuel consumption including the equivalent fuel consumption of the power battery, and the optimal control sequence of the diesel generator is obtained by means of a dynamic programming method. Thus, the minimum fuel consumption value of diesel generator in the whole navigation cycle is calculated. The simulation results show that the proposed method can effectively reduce the fuel consumption of hybrid power system compared with the on-off control strategy.
