Abstract
An energy operation support device includes: an optimization calculation unit; and operation guideline transmission units. The calculation unit sets an operation condition of an energy facility as a determination variable based on information obtained from a result value/prediction value acquisition unit, unit price information acquisition unit, and functioning information acquisition unit, constitutes a balance condition of an energy utility, and adds a shortage amount determination variable of the energy utility to the generation variable side of the balance condition and establishes a constraint condition. Then, the unit sets an objective function containing the total cost for the energy operation of a steel works and the shortage amount determination variable and arithmetically operates the determination variable so the objective function asymptotically approaches the optimum value to satisfy the constraint condition. The transmission units transmit an operation guideline to an operator based on the shortage amount arithmetically operated in the calculation unit.
