Modeling Innovative Thermal Power Generation Systems for the Energy Transition with Modelica: an Open Source and Flexible Solution

In this work, the authors address the challenges of modeling innovative thermal power generation systems in the energy transition context. Their peculiar designs and components call for a more flexible modeling environment. In this respect, Modelica language has emerged in the last years as a solid and reliable choice to model such power plants. Through the description of the SOS-CO
