? A mixed integer non linear programming (MINLP) model is presented for structure optimization of steam power systems. The presentation accounts simultaneously for the non convex non linear cost function, the complicated relations of steam properties, the constraints of turbine work generating process, as well as the logical constraints of 0 1 integer variables. By means of the improved genetic algorithm, the results of a numerical example show that the model and the algorithm involved are effective.
