Configuration of energy storage is conducive to the advantages of new energy resource-rich areas, to achieve large-scale consumption of clean energy, hydrogen energy storage is a new type of energy storage in the power system, with clean and non-polluting, large storage capacity, high energy density and other advantages. Adopting the hybrid energy storage method of battery combined with hydrogen energy storage can ensure the short-term demand of the load as well as longterm storage of a large amount of backup energy. In the planning and design process, determining the topology of the system, reasonably analysing the operation of each unit and establishing relevant mathematical models are the basis for the research on the optimal allocation of system capacity. In this paper, the structure and model of wind-hydrogen storage system are studied, the topology diagrams of off-grid type and grid-connected type are given, the principles of wind turbine, photovoltaic battery, storage battery and hydrogen storage are introduced, and the mathematical model is constructed, which lays the foundation for further research on the optimal configuration of the system.
