While the power plant is running, the processor may be configured to automatically collect operational data associated with the power plant. The collected data may be stored in a predefined location. Furthermore, the processor may be configured to select stable data from the operational data to coincide with output data associated with a power plant model. One or more parameters of the power plant model may be modified, and at least one difference may be minimized between the output data associated with the power plant model and a measured value in the power plant operational data.
