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
