Abstract
A hydrogen production system and a method for controlling the same are provided. A renewable energy power generation system supplies electric energy to a hydrogen production device. The hydrogen production device discharges acceptable-purity hydrogen to the main hydrogen branch and discharges unacceptable-purity hydrogen to the mixed hydrogen branch. The mixed hydrogen branch receives high-purity hydrogen. The mixed hydrogen branch includes two valves to respectively control volumes of the high-purity hydrogen and the unacceptable-purity hydrogen flowing into the hydrogen mixing device in the mixed hydrogen branch, to control mixed hydrogen in the hydrogen mixing device to be the acceptable-purity hydrogen. The acceptable-purity hydrogen in the hydrogen mixing device is discharged to a purification branch in the main hydrogen branch, or a purification branch in the mixed hydrogen branch.
