The invention provides a new energy ship light-hydrogen-electricity hybrid power system management method. The method comprises the following steps that S1, energy management strategies in different states are determined through a finite-state machine, EMCS and MPPT; s2, the photovoltaic module adopts an MPPT maximum power point tracking control method based on a perturbation and observation method to determine disturbance U needing to be applied, and the storage battery adopts an ECMS to determine fuel consumed by a minimum fuel cell in different states and a correction coefficient alpha needed when the SOC of the storage battery is maintained; and S3, acquiring real-time required power of the ship, and determining energy management strategies under different state points by adopting a finite-state machine according to the maximum output power of the photovoltaic module, the storage battery and the fuel cell. By improving the state and the state number of a finite-state machine and introducing an ECMS, the selectivity of an electric driving mode is increased, and a more refined energy management strategy is achieved.

    本申请提出了一种新能源船舶光‑氢‑电混合动力系统管理方法,包括以下步骤:S1、采用有限状态机、EMCS和MPPT确定不同状态下能源管理策略;S2、光伏模块采用基于扰动观察法的MPPT最大功率点跟踪控制法确定所需施加的扰动U,蓄电池采用ECMS确定不同状态下最小化燃料电池所消耗的燃料以及维持蓄电池的SOC时所需的修正系数α;S3、获取船舶实时需求功率,根据光伏模块、蓄电池和燃料电池最大输出功率,采用有限状态机确定不同状态点下能源管理策略。通过改进有限状态机的状态和状态数以及引入ECMS来增加电力驱动模式的可选择性,实现更加精细化的能源管理策略。
