Abstract:
The purpose of the present invention is to make a self-consignment plan, for an entity comprising a power receiving business establishment and a power generating business establishment, by considering the uncertainty of a plurality of production schedules of a manufacturing facility, and also to keep planned-value balancing by changing the power demand through the adjustment of the production schedules. An energy management device in an entity comprising a power generating business establishment and a power receiving business establishment which are connected to a power system is characterized in that: an EMS is installed in the power generating business establishment and the power receiving business establishment, and an AEMS is installed in the entity; the EMS of the power receiving business establishment predicts the power transition for each production line of the power receiving business establishment on a scheduled date and categorizes the operation schedules of the production lines thereof on the scheduled date into a definite schedule, indefinite schedule, and an adjustable schedule; and the AEMS, on the basis of the categorized operation schedule and the power transition on the scheduled date which have been reported from the EMS of the power receiving business establishment, sets a definite demand and a maximum demand considering the indefinite schedule on the scheduled date, and sets a self-consignment plan output to the power receiving business establishment within the range of the minimum self-consignment amount, which is obtained as the difference between the maximum demand and the contracted power of the power receiving business establishment, and the definite demand; and the EMS of the power generating business establishment generates power according to the self-consignment plan output set by the AEMS.
