This paper presents a method to determine the optimal operational parameters of a combined cycle power plant, using a dynamic simulation program and nonlinear optimization technique. This proposal method combines the optimization calculation based on the nonlinear programming method with the dynamic simulation. The operational design is optimized in consideration with the plant dynamic characteristics, i.e. machines thermal stress, start-up time and energy loss, etc. are predicted by the dynamic simulation. An application for the optimization of plant start-up scheduling is able to reduce the start-up time and energy loss with keeping the machines thermal stress under the allowable values. The result shows the start-up time and energy loss are reduced by 21.7% and 19.5% during the gas turbine loading process, compared with a conventional heuristic method.
