The invention relates to the technical field of renewable energy hydrogen production, in particular to an alternating-current bus renewable energy hydrogen production power supply device and a control method thereof, and the device comprises a hydrogen production power supply assembly which has a first hydrogen production mode, a second hydrogen production mode and a third hydrogen production mode; the matching component is used for matching the optimal mode of the hydrogen production power supply component from the first hydrogen production mode to the third hydrogen production mode according to the user budget, the expected service life and/or the power grid auxiliary service capability; and the control assembly is used for controlling the hydrogen production power supply assembly to produce hydrogen by using the renewable energy of the alternating-current bus according to the optimal mode. Therefore, the problem that an existing high-capacity renewable energy hydrogen production power supply system is lack
