The invention discloses a method of improving tracking photovoltaic power generation output characteristics based on hydrogen and battery hybrid energy storage. The method comprises the steps of: S100, formulating a next-day photovoltaic output plan according to the short-term photovoltaic prediction power, and correcting the next-day photovoltaic output plan according to the SOC of an energy storage battery at night of the day, S200, dividing scheduling modes into main scheduling and coordinated scheduling according to the SOC of the energy storage battery, selecting a different scheduling mode according to the state of charge interval of the SOC of the energy storage battery in real-time scheduling, and tracking the photovoltaic planned output, and S300, taking the photovoltaic output plan as the premise by next-day scheduling and controlling a hydrogen electrolysis cell and the energy storage battery for charge and discharge according to the scheduling mode. The method can perform flexible switching between a main scheduling scheme and a coordinated scheduling scheme, realizes accurate tracking of photovoltaic planned output, reduces fluctuation of grid-connected input power ofa photovoltaic power station, relieves frequency modulation pressure of a system unit, and improves the utilization rate of light energy.
