    Abstract: A power control apparatus capable of stable transition of a set voltage is provided. A power control apparatus includes a DC to DC converter connected to a DC bus line, a communication unit that communicates with another power control apparatus, and a control unit that controls power interchange with the other power control apparatus through the DC bus line, in which the control unit controls at least a control mode and a droop rate, the control mode includes a first mode for controlling a voltage of the DC bus line, a second mode for controlling a current flowing through the DC bus line, and a third mode for stopping the power interchange, and when the control mode is shifted from the first mode to the second mode or the third mode, the control unit controls the droop rate to be set to a predetermined value other than 0%.

    Abstract: In one embodiment, there is provided a power interchange system for distributing direct current (DC) electrical power. The power interchange system comprises a plurality of nodes comprising a first node and a second node. The first node comprises a first communication device and a first power source to power the first communication device. The second node comprises a second communication device and a second power source to power the second communication device. The power interchange system further comprises a wired cable connecting the first node and the second node. The wired cable comprises at least one first wire to convey DC power from the first power source of the first node to the second node to power the second communication device or from the second power source of the second node to the first node to power the first communication device.
