Photovoltaic power has great fluctuation due to weather which,in case of being directly connected to the grid,will seriously affect the power quality of the grid. For reducing the influence of grid-connected power of PV station on the grid,a method based on Hydrogen and battery hybrid energy storage to improve the tracking of photovoltaic power generation output characteristics is proposed. Firstly,the Gaussian func-tion is used to approximate the predicted PV power to form the PV output plan for the next day. And the PV output plan is modified in accordance with the SOC size of the battery in the early morning and the adjust-ment flexibility of Hydrogen energy storage. Considering the operation state of Hydrogen energy storage and battery energy storage,a real-time scheduling scheme including master scheduling and coordinated sched-uling is designed. Finally,an example is given to verify the effectiveness of the proposed method.
