Zusammenfassung:	Systems 10 and methods for loading a steam turbine 14 are provided. A method may include: receiving a turbine loading factor; receiving a current steam turbine exhaust temperature; determining a steam flow ramping rate parameter 205 and a steam temperature ramping rate parameter 210 based at least in part on the turbine loading factor and the current steam turbine exhaust temperature, wherein the steam flow ramping rate parameter and the steam temperature ramping rate parameter are determined based at least in part on an inverse relationship between the steam flow ramping rate parameter and the steam temperature ramping rate parameter. The method may further include controlling at least one of: (a) steam flow to the steam turbine based at least in part on the steam flow ramping rate parameter; or (b) steam temperature to the steam turbine 14 based at least in part on the steam temperature ramping rate parameter 210.
