In the electricity market of today; with increasing demand for electricity production on short notice; the combined cycle power plant stands high regarding fast start-ups and efficiency. In this paper it has been shown how the dynamic start-up procedure of a combined cycle power plant can be optimized using JModelica. org; proposing a way to minimize the start-up time while maximizing the power production during start-up. The physical models have been developed in Modelica; adapted to suit optimization purposes and extended to optimization problems. Constraints keeping the lifetime consumption of critically stressed components under control are limiting factors. The plant models have been successfully optimized to full load.
