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.
