Electrical power engineering

We focus on efficient energy use, reliable and highly available systems and the clever incorporation of de-centralized energy generation.

Electricity comes out of the plug socket as a matter of course. Securing a reliable, low-cost and sustainable supply of electrical energy entails huge development needs.

Grid integration of de-centralized generation plants and storage systems

We develop intelligent methods for regulating and controlling resources in the electricity grid, so that users can save costs and the burden on the grid can be reduced. Some examples include:

  • Individual or networked management of battery storage systems, water heaters, PV systems or other resources
  • Control methods and tariff models for energy networks, to ensure the desired load profile is maintained
  • Optimised inclusion of switchable transformers and photovoltaic inverters to stabilise distribution grids
  • Software tools to determine the load capacity and behaviour of distribution grids

Wind energy use at high altitudes

At high altitudes, the wind blows stronger and, more importantly, far more consistently than further down. In partnership with the IAST, the spin-off company TwingTec is developing wind energy systems that capitalise on this effect.

Characterisation and optimisation of power electronics components

Power electronics components are subjected to great stress due to high power densities and temperatures, which limits their life time. This applies in particular to new silicon carbide (SiC) components. The Institute of Aerosol and Sensor Technology is examining and optimising the reliability of power electronics components and systems. There are a series of test setups, measurement methods and simulation tools available for this.

Selected Project

SwiSS-Transformer

For the future electricity supply, an interdisciplinary research team is developing a dynamic transformer.
