Abstract: Around the diversified utilization of distributed wind power, implement the rapid development of green electricity-green hydrogen low carbon economy, An integrated wind-hydrogen coupling system including permanent magnet synchronous direct-drive wind turbines, PEM electrolyzer, high-pressure hydrogen storage tanks and hydrogen fuel cells coupled to AC buses has been constructed. According to the physical constraints of each unit and the typical operating scenario mode, a wind-hydrogen coupled energy management strategy with nine operating conditions is proposed, which enables the power difference between the distributed wind power and the load demand to be completely absorbed or compensated by the PEM electrolyzer or the fuel cell, and ensures the power dynamic balance of the distributed wind power system. The simulation results show that the proposed energy management strategy can effectively coordinate the power flow between the distributed wind power and electrolyzer and the load, and ensure the coordinated and stable operation of the wind-hydrogen coupled integrated system at multiple time scales.
