動特性解析によるガスタービン複合発電システムの急速負荷変化時の運用性評価

抄録

The use of renewable energy sources (REs) such as solar and wind power is necessary to reduce the CO₂ emissions. However, the fluctuating power output of REs renders the electric grid unstable. Gas turbine combined cycle power generation (GTCC) with a rapid start-up and high ramp rate is a potential solution to compensate for the load fluctuation. In this paper, dynamic simulation was conducted to validate the effect of increasing the load change rate on the steam-bottomed cycle of the proposed GTCC and methods to improve operating characteristics at increased load were discussed.
