The application of renewable energy-hydrogen production has entered a rapid development stage, and the wind-hydrogen-storage system can provide energy supply for multiple application scenarios, which is an important direction for the future development of renewable energy application technology. This paper focuses on the technical problems in the current independent operation wind-hydrogen-storage system application research, and elaborates on the current development status and challenges of technology from three aspects: system operation characteristics and modeling, electrical topology structure, and flexible operation control. It also explores the future development direction of key technologies, aiming to provide reference and guidance for the research of large-scale renewable energy-hydrogen production energy supply system technology that achieves high efficiency, low cost, and adaptability to multiple application scenarios.
