Load adjustment method, load adjustment device, and program

A load adjustment device, comprising:

• a bid-related information acquisition part configured to acquire bid-related information including at least one of information on electricity demand in an electricity trading market or forecast information on electricity prices in the electricity trading market;
• a bidding process part configured to execute a bidding process, the bidding process including transmitting data indicating a commodity to the electricity trading market, the commodity having response time of a gas turbine to an output command or minimum bid amount;
• a parameter acquisition part configured to acquire a warm-up parameter when it is determined that a successful bid has been made for the commodity, the warm-up parameter indicating an amount of warm-up of the gas turbine during operation under load;
• an upper limit determination part configured to determine an upper limit of a load increase rate in accordance with the warm-up parameter;
• and
• an operation command part configured to output an operation command to increase the load of the gas turbine to a first load at a first load increase rate, then further increasing the load to a second load which is larger than the first load at a second load increase rate which is larger than the first load increase rate after performing warm-up operation in a state that the load is maintained at the first load, and
• wherein the second load increase rate is equal to or below the upper limit of the load increase rate.

A non-transitory computer readable medium recorded with a program configured to cause a computer to execute:

• a process of acquiring bid-related information including at least one of information on electricity demand in an electricity trading market or forecast information on electricity prices in the electricity trading market;
• a process of executing a bidding process, the bidding process including transmitting data indicating a commodity to the electricity trading market, the commodity having response time of a gas turbine to an output command or minimum bid amount;
• a process of acquiring a warm-up parameter when it is determined that a successful bid has been made for the commodity, the warm-up parameter indicating an amount of warm-up of the gas turbine during operation under load;
• a process of determining an upper limit of a load increase rate in accordance with the warm-up parameter;
• and
• a process of increasing the load of the gas turbine to a first load at a first load increase rate, then further increasing the load to a second load which is larger than the first load at a second load increase rate which is larger than the first load increase rate after performing warm-up operation in a state that the load is maintained at the first load, and
• wherein the second load increase rate is equal to or below the upper limit of the load increase rate.
