The project “Industrial Process Steam Supply – Demonstration of an Ultra-Dynamic Thermal Energy Storage” (ISSDemo) focuses on the practical implementation and demonstration of an ultra-dynamic thermal energy storage system for industrial process steam supply. The target temperature range is 250 °C – 500 °C, with a capacity of the demonstrator of about 1 MWh.
This master´s thesis addresses the modelling and simulation-based analysis of the underlying storage con cept. A dynamic model developed in Dymola using Modelica will be used to investigate the charging and discharging behaviour of an electrically heated metallic latent heat storage system, evaluate various operating scenarios and, if applicable, validate the model using existing measurement or simulation data.
Modelica is an object-oriented, equation-based modelling language that is particularly well suited for the multiphysical modelling of complex energy systems, as it enables the consistent coupling of electrical, thermal and fluid-dynamic domains. Using Dymola as the simulation environment allows for efficient model implementation, parameter studies and transient analyses. The thesis comprises:
- Familiarization with the physical fundamentals of latent heat storage systems and the specific design of
the storage system under consideration - Design and development of a dynamic storage model in Modelica (electric heating, heat transfer, phase
change, steam supply) - Conducting simulation studies to analyse charging/discharging processes and selected operating cases
- If possible, parameterization and calibration of the model based on existing design, measurement or sim
ulation data.
