A strategy for the solution of the optimization problem of minimum cost of combined cycle gas turbine power plants is presented. Specic relationships, valid at the optimal solution, among selected decision variables are used to introduce new constraints to the optimization problem. Then, the feasible region is reduced to a single point", and the resolution strategy becomes equivalent to solving the resultant set of non-linear equations system and constraint equations so achieved to optimize the system. This approach can also be used to achieve reduced models for real time optimization problems.
