Master Thesis - Flexibility Potentials in Buildings Based on Automated Model Generation

Your Job:

The building sector offers a large potential for energy savings and the realization of the climate and energy consumption goals defined by Germany and the EU. Using building simulation models, the energy consumption during operation can be simulated from different angles. Based on a toolchain, which automatically generates building Modelica models based on an intuitive language for room descriptions developed at the institute, campus building plans and measurement data, simulation should be conducted with respect to different aspects that are playing an ever greater role in future buildings. In this work, the flexibility potential of buildings should be analyzed, more specifically, the potential to reduce or shift loads. The motivation results from an increasing share of renewable energy sources (e.g., solar and wind energy) and the resulting stress on the electrical grid. Building energy systems as large energy consumers (and producers) incorporate several different technologies for load shifting, as well as storage capabilities (actively within thermal and electrical storage, passively within the building thermal mass) and flexibility potentials within the comfort ranges (e.g., range of the indoor air temperature, which is comfortable for the user). Tools for conducting the work are Python for implementation of the analysis tools and partly the simulation software Dymola for simulation and modeling of the Modelica building models.
