Abstract

A simulator of combined cycle power plant based on phenomenological equations, developed in Matlab-SIMULINK, is presented. Then, a new non-linear control strategy based on minimizing the operational costs with environmental and operational constraints of the thermal power plant is designed. The optimization problem with constraints is solved using a non linear dynamic model and the predictive control theory. The solution is given by the optimal set points of the regulation level, i.e., the set points of the PI controllers.
