ABSTRACT:
For calculating optimum operation parameters of a BTG plant including a plurality of boilers having a linear input/output characteristic between an incoming fuel and steam output and a plurality of turbines having a non-convex input/output characteristic between the incoming steam which is an output of the boiler and power output, a dynamic programming process is performed twice and a linear programming process is performed once with respect to the steam and power to find, as an optimum solution, the power output of the turbines. Finally, an optimum solution is found in which a total fuel cost is minimized.
