Economic optimal control for a combined cycle power plant boiler

A boiler simulator of a combined cycle power plant based on phenomenological equations, developed in Matlab-SIMULINK, is presented. Then, a new economical optimal control strategy based on minimising the operational costs of a boiler is designed and implemented. The solution is given by the optimal set points of the regulation level, i.e., the set points of the PI controllers. The optimisation problem is solved using the predictive control theory.
