1. An energy-Internet system, comprising:
an alternating-current (AC) side energy routing conversion device comprising a plurality of first route ports and a plurality of third AC/DC converters, wherein first ends of the plurality of third AC/DC converters are connected to each other, and wherein a second end of each of the third AC/DC converters is used as a first route port of the plurality of first route ports;
a direct-current (DC) side energy routing conversion device comprising a plurality of second route ports and a plurality of third DC/DC converters, wherein first ends of the plurality of third DC/DC converters are connected to each other, wherein a second end of each of the third DC/DC converters is used as a second route port of the plurality of second route ports, and wherein each of the second route ports is connected to a corresponding first route port by a corresponding DC busbar; and
a plurality of energy devices, each connected to the DC busbar through a corresponding first AC/DC converter or a first DC/DC converter;
wherein the AC side energy routing conversion device and the DC side energy routing conversion device are configured to collect energy information of the energy devices, and are configured to adjust energy of each of the energy devices on a basis of energy balance constraint conditions.
