1. A power supplying device, comprising:
- a controller configured to;
receive, from a first device of a plurality of devices, a first request to supply power through a direct-current bus line, wherein DC power flows through the direct-current bus line;
determine, based on the first request, whether the power supplying device is able to supply the power to the first device;
transmit a response to the first device based on the determination that the power supplying device is able to supply the power, wherein the response indicates the power supplying device as a candidate to supply the power;
determine one of a presence or an absence of a right to control the direct-current bus line, wherein the presence of the right to control the direct-current bus line indicates that a second device of the plurality of devices has the right to control the direct-current bus line;
acquire the right to control the direct-current bus line, based on the absence of the right to control;
notify the plurality of devices of the acquisition of the right to control the direct-current bus line; and
control the supply of the power through the direct-current bus line to the first device based on the acquired right to control the direct-current bus line.
