Abstract
A direct-current coupling hydrogen production system includes at least one electricity generation system and multiple hydrogen production electrolyzer systems. The electricity generation system includes: a controller, N renewable energy systems, multiple conversion systems and a power switching unit. The power switching unit includes N input ports and M output ports. The controller is configured to control the power switching unit to supply the multiple hydrogen production electrolyzer systems through its output ports with electrical energy received through its input ports, or is configured to control the power switching unit to collect electrical energy received through its input ports and to supply the multiple hydrogen production electrolyzer systems through its output ports respectively corresponding to the hydrogen production electrolyzer systems with the collected electrical energy.
