Figure Legend:
Start-up sequence for a traditional control method of the GTs and the ST. GT start-up curves are shown for the first GT. The second
GT is omitted for simplification. The GT speed and load are controlled by adjusting the gas control valves (GCVs). The ST speed and
load are controlled by adjusting the steam control valves (SCVs).
