Modeling and optimization of complex systems traditionally have
required significant programming efforts in order to encode the
model dynamics, the cost functions and the constraints in a format
suitable for state of the art numerical algorithms. The availability
of dedicated languages for physical modeling has made the design
process simpler, but often tools have been limited to a particular
optimization algorithm. In this paper, we present a case study where
a combined cycle power plant model has been developed using first
principles in the modeling language Modelica. Based on the model, an
optimal control problem for the start-up of the power plant has been
formulated in the Optimica extension and solved using the open
source software The results demonstrate how
high-level modeling languages and tools can be used to bridge the
gap between the engineering need for intuitive description formats
and the interfaces of efficient numerical algorithms.
