DEVICE, SYSTEM, AND METHOD FOR MANAGING POWER

摘要

In the present invention, a power source provided to a plurality of items of equipment is effectively used. The power-management device is provided with a communication unit and an assessment unit. The communication unit transmits to a communication network a first prediction datum showing the predicted value of the balance of supply and demand of electric power in relation to a first item of equipment connected to an electric power system having the power source and, when a message requesting power accommodation is received from a different power-management device that transmits to the communication network a second prediction datum showing the predicted value of the balance of supply and demand of electric power of a second item of equipment connected to the electric power system, receives the second prediction datum from the communication network. The assessment unit assesses whether power accommodation is possible on the basis of the first prediction datum and the second prediction datum. If power accommodation is assessed to be possible, the communication unit transmits a message approving the request to the other power-management device.
