POWER DEMAND AND SUPPLY GUIDANCE DEVICE AND POWER DEMAND AND SUPPLY GUIDANCE METHOD

摘要

Provided is a power demand and supply guidance device (200), wherein: a production plan obtaining unit (221) obtains a production plan of a manufacturing plant that belongs to a steelmaking plant; a power estimation unit (222) calculates an estimated power amount which is an electric power amount estimated to be used in each manufacturing plant on a time-series basis on the basis of the obtained production plan, and totals the estimated electric power amounts of the manufacturing plants to calculate an estimated power amount of the whole steelmaking plant; a generated/purchased power amount determination unit (223) determines a generated power amount to be self-generated, a purchased power amount to be purchased from an electric power utility company, and a production reduction rate on the basis of the estimated power amount of the whole steelmaking plant and the estimated power amounts of the manufacturing plants; a visualization unit (225) displays time series variations of the estimated power amounts of the manufacturing plants, the estimated power amount of the whole steelmaking plant, the generated power amount, the purchased power amount, and the production reduction rate on a monitor (263); and an alarm notification unit (224) makes an alarm notification of production reduction.
