An energy internet system, an energy routing conversion device, and an energy control method related to the field of energy information are provided. The alternating current (AC) side energy routing conversion device 110 of the energy Internet system includes a plurality of first route ports, the direct current (DC) side energy routing conversion device 120 includes a plurality of second route ports, Each second route port is connected to a corresponding first route port by a corresponding DC bus bar. The plurality of energy devices 130 are connected to the DC bus bar by a corresponding first AC/DC converter or a first DC converter. The AC-side energy routing conversion device 110 and the DC-side energy routing conversion device 120 collect energy information of the energy device 130, and the energy is determined based on energy balance constraint conditions. Adjust the energy of the device 130. This achieves a balanced operation of the energy exchange of the energy internet system and ensures the stability of the system.
