In order to specify an optimization problem in Optimica, the new specialized class optimization is used. Inside such a class, Optimica constructs, as well as Model-ica constructs Optimica — An Extension of Modelica Supporting Dynamic Optimization.

Optimica extends Modelica with language constructs that enable formulation of dy- namic optimization problems based on Modelica mod- els. There are several important design problems that can be Skip to main content.

an Optimica specication can be formulated, see List-ing 2. Since Optimica is an extension of Modelica, language elements valid in Modelica are also valid in Optimica.

Python is compatible with Optimica and it is po s-sible to interact with Modelica and Optimica models through Python scripting (the Python interface of the Jmodelica.org platform is great for this). For exa m-ple, it enables the possibility to do parameter mani p-ulation s and to perform simulation and optimiz ation for a variety of setups.

The Optimica extension is supported by a prototype compiler, the Optimica compiler, which has been used successfully in case studies.

Optimica consists of a few but powerful new language constructs that enable the user to express optimization problems using high-level descriptions on par with Modelica. Using the Optimica extension, optimization interval, cost function, constraints and information related to the numerical algorithm used to solve the problem can be specified. OPTIMICA compiled steady state Modelica models exposes • Iteration variables and residuals • Cost function • Optimization variables (free variables) Interface to numerical optimization routine IPOPT available Optimization use cases • Component design/sizing • Set-point optimization • Parameter estimation STEADY-STATE OPTIMIZATION Python is compatible with Optimica and it is po s-sible to interact with Modelica and Optimica models through Python scripting (the Python interface of the Jmodelica.org platform is great for this).
