The invention discloses a hybrid power ship energy control method considering battery life attenuation, and the method comprises the steps: obtaining a navigation working condition of a hybrid power ship in a certain fixed water area, carrying out the global dynamic planning in the working condition, and obtaining a battery SOC change track enabling a target function to be minimum in the working condition; and based on the A-ECMS, solving the current optimal power distribution between the diesel generator and the power battery in real time by taking the minimum real-time equivalent oil consumption as a target function, and the method is applied to real-time control. According to the method, the fuel consumption and the battery life are considered, the weighting coefficient is introduced, the fuel consumption and the battery life are subjected to coordinated control, and the battery life is effectively prolonged while the fuel consumption is not greatly changed.
本发明公开了一种考虑电池寿命衰减的混合动力船舶能量控制方法,该方法包括:获取某固定水域内混合动力船舶的航行工况,并在该工况内进行全局动态规划,得到该工况内使得目标函数最小的电池SOC变化轨迹;基于A‑ECMS,以实时等效油耗最小为目标函数,实时求解当前最优的柴油发电机和动力电池之间的功率分配,应用于实时控制。本发明兼顾了燃料消耗和电池寿命,通过引入加权系数,对燃油消耗和电池寿命进行协调控制,保证在燃油消耗变化不大的同时有效延长电池寿命。
