Combined Cycle Power plant takes advantage of the efficiency, fast startup, and small environmental impact. The operation design of this plant is required to make best use of this plant advantage, A large-scale non-linear mathematical model of this plant was developed to check the plant condition. This simulation model was combined with the optimization using Rosenbrock method. The operation design is optimized in two steps; _??_Step 1_??_: Some points of plant condition can be checked roughly._??_Step 2_??_: This plant operation is optimized to design using Rosenbrock method. This optimization is applied to design the combined cycle power plant operation. It is confirmed that this methods is effective for the design of plant operation. From this study, plant operation can be designed with this optimization to make best use of this plant advantage. Then operation design point is decided using the optimization method on some evaluation instead of heuristic method.
