Abstract
A control device includes a reception unit configured to receive a load schedule indicating a load in the future of a combined cycle plant, a steam temperature control unit configured to control a temperature of steam flowing into a steam turbine, and a fuel control unit configured to control a flow rate of fuel supplied to a gas turbine. The steam temperature control unit is configured to output a command indicating an amount of operation for decreasing the temperature of the steam to a steam temperature regulator prior to a load decrease time at which the load is to be decreased in the load schedule.
