ENERGY MANAGEMENT DEVICE, ENERGY MANAGEMENT METHOD, AND ENERGY MANAGEMENT PROGRAM

摘要

An energy management device capable of readily adapting to changes in a system that manages power supply and demand. This energy management device comprises the following constituent elements: a first registration unit that registers a first energy management device that has returned information indicating registration permission, as a host energy management device; a second registration unit that registers a second energy management device that has received a registration request, as a slave energy management device; a first reception unit that receives energy supply and demand volumes and energy supply and demand adjustable volumes, from a plurality of slave energy management devices; an aggregation unit that aggregates the volumes; a first transmission unit that sends the aggregation results to the host energy management device; a second reception unit that receives energy supply and demand adjustment volumes calculated on the basis of the aggregation results, from the host energy management device; a proportional division unit that proportionally divides the energy supply and demand adjustment volume among the slave energy management devices; and a second transmission unit that sends the proportionally divided energy supply and demand adjustment volume to each slave energy management device.
