Abstract: A model-based control system is configured to select a desired parameter of a machinery configured to produce power and to output emissions and to select an emissions model configured to use the desired parameter as input and to output an emissions parameter. The model-based control system is additionally configured to tune the emissions model via a tuning system to derive a polynomial setpoint, and to control one or more actuators coupled to the machinery based on the polynomial setpoint.

Abstract: Systems and methods for NOx prediction in a power plant are disclosed. According to one embodiment of the disclosure, a method for NOx prediction in a power plant can be provided. The method may include receiving parameters associated with operation of a combined gas turbine and steam turbine in a power plant, wherein the parameters comprise a combined power output value; determining a steam turbine power output value; based at least in part on the steam turbine power output value, estimating a gas turbine power output value. The method may further include: based at least in part on an input matrix, determining a set of modeled gas turbine parameters. The method may further include based at least in part on omission of the estimated gas turbine power output value from the input matrix, determining a modified set of modeled gas turbine parameters; based at least in part on the modified set of modeled parameters, determining a NOx emission value associated with the power plant; based at least in part on the NOx emission value, determining a control action for the power plant; and facilitating the control action for the power plant.
