The invention discloses a non-grid-connected wind power electrolyzed water hydrogen production system and a cooperative control method thereof. The system includes: a wind-driven generator set, quasi-Z-source converter devices, a DC bus, a hydrogen production device, and a control unit. Each wind-driven generator in the wind-driven generator set is connected to the DC bus through a corresponding quasi-Z-source converter device. The hydrogen production device is connected to the DC bus and includes n parallel branches. Each parallel branch has m hydrogen production units connected in series. Each hydrogen production unit includes multiple electrolytic cells. Each parallel branch has a branch switch connected in series. Each hydrogen production unit has a power switch connected in parallel.The control unit is configured to monitor the operating status of the wind-driven generator set, adjust the voltage level of the DC bus, and turn on/off the branch switches and the power switches. Thenon-grid-connected wind power electrolyzed water hydrogen production system and the cooperative control method thereof can ensure the adaptability of a source end and a load end in a hydrogen production process, improve hydrogen production efficiency, and reduce production costs.
