| description | Methods and apparatus to optimize turbine ramp rates are disclosed herein. An example method includes predicting a setpoint for a turbine rotor over a prediction horizon. The example method includes predicting a surface temperature profile of the turbine rotor for the prediction horizon based on the predicted setpoint via an empirical data model. The example method also includes predicting a first stress profile for the turbine rotor based on the surface temperature profile. The example method includes performing a comparison of the first stress value to a second stress value and dynamically adjusting the setpoint based on the comparison. |
