Linearization for Analysis of a Hydropower Model using Python API for OpenModelica

Even though almost all processes in the real world are described by nonlinear models, nonlinear theory for analysis of these models is far less developed than the theory for linear models. Therefore model linearization is important in order to make efficient analysis tools for these models. This paper describes the possibility of automatic linearization in Python for a hydropower system modeled in OpenModelica using our in-house hydropower Modelica library OpenHPL. Linearization is made using a Python API. Simple uses of the linearized model for analysis and synthesis are indicated.
