To effectively determine premises as a counterpart for transmission or reception of power in a case of interchanging direct-current power between respective premises A control device () according to the present invention includes a power control unit () configured to determine a node that performs transmission or reception of direct-current power to or from an own node by using profile information indicating a power usage state of each of the nodes exchanging direct-current power with each other.

Device and method for controlling transfer of DC power between nodes

A method of operating a first battery server for use with a first node of a power interchange system that distributes direct current (DC) power between nodes, wherein each node of the nodes comprises a storage battery to store electrical energy and a battery server to control transmission of DC power from the storage battery of the node to one or more other nodes and to control receipt of DC power at the node from one or more storage batteries of one or more other nodes. The method comprises, in response to detecting that a state of charge of the first storage battery and/or a usage rate of power satisfies one or more conditions, requesting that a master node of the power interchange system control transmission of power from another node of the nodes to the first node, wherein the master node is one of the nodes.
