Research

The dominant work area at our department next to Teaching is the area of Research, in which we also cooperate with non-university partners.

Herein the following focuses of research need to be mentioned:

  • Employing New Methods and System Components for Power Supply, especially Superconductive Equipment as well as Systems for the Use of Regenerative Engergies
  • Optimization and Identification of Models for Electric Power Systems
  • Computersimulations of Electric Power Systems, especially Strategies for the Efficient Simulations of Non-stationary Operational Behaviour (Time-Scale-Modeling)
  • Application of Neuronal Networks and other Methods of Soft Computing in Power Supply
  • Analysis of Operational Conditions of Electric Power Systems, especially Harmonic Overtone Loads and Circuit Feedback (Power Quality)
  • Calculating and Measuring Electromagnetic Fields with Electric Equipment

The Institute is partner of the Lower Saxony Wind Power Competence Centre ForWind
