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...
This work considers the optimization of a combined cycle power plant by using supervisory controllers for the turbines and boiler. The design of a hybrid predictive supervisory controller for a gas turbine is based on a state space discrete model including the switching behavior of a PI control system. The control design is based on an objective function that represents the economic and regulatory...
