The invention discloses a marine hybrid power system control method, device and system and a ship. The method comprises the following steps: judging the current required load power of an electric load and the self state of a lithium battery pack; if the current required load power is smaller than the first preset value and the state of the lithium battery pack meets the pure electric operation condition, the power supply mode of the ship power grid is switched into a pure electric mode, and the pure electric mode is that only the lithium battery pack supplies power; if the current load power is smaller than a second preset value and meets the pure methanol operation condition, the power supply mode of the ship power grid is switched into a pure methanol mode, and the pure methanol mode is that only a methanol generator set supplies power; and if the conditions are not met, switching to a hybrid power mode for working, and supplying power by the lithium battery pack and the methanol generator set together in the hybrid power mode. According to the technical scheme of the embodiment of the invention, the output of each power source is flexibly adjusted according to the load required by the ship, the operation economy of the system is improved, and the pollutant emission is reduced.

    本发明公开了一种船用混合动力系统控制方法、装置、系统及船舶。该方法包括:判断电力负载的当前所需负载功率、锂电池组的自身状态;若当前所需负载功率小于第一预设值,且锂电池组的自身状态满足纯电运行条件,则将船舶电网的供电模式切换为纯电模式,纯电模式为仅由锂电池组供电;若述所当前负载功率小于第二预设值,且满足纯甲醇运行条件,则将船舶电网的供电模式切换为纯甲醇模式,纯甲醇模式为仅由甲醇发电机组供电;若不满足以上条件,则切换为混动模式进行工作,混动模式为由锂电池组和甲醇发电机组共同供电。本发明实施例的技术方案实现了根据船舶所需负荷,灵活调节各动力源的输出,提高系统运行经济性,减少污染物排放。
