【摘要】:針對由發(fā)電機組和動力電池兩種不同的電源組合而成的混合動力船舶供電系統(tǒng),在功率需求給定的情況下,合理地分配兩種電源的功率輸出,使得混合動力船舶在整個航行周期內(nèi)的總耗油量達到最小是能量管理系統(tǒng)需要解決的問題。采用一種動態(tài)規(guī)劃的方法優(yōu)化兩種電源的功率輸出比重,通過建立包含動力電池等效油耗的最小油耗量的目標函數(shù)得到柴油發(fā)電機的最優(yōu)控制序列,從而計算出整個航行周期內(nèi)柴油發(fā)電機的最小油耗值。仿真結(jié)果表明,與開關(guān)式控制策略相比,該方法能有效降低混合動力系統(tǒng)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.
