Planning and operation of grids

Planning and operation of electrical grids have undergone a long process of evolution since the beginning of electrification. More and more generators and consumers have been connected to the electrical power supply networks in order to ensure, for example, the highest possible system security. The essential components of the current system are still conventional large-scale power plants, which do not only provide a lot of power, but also make a significant contribution to safe operation with their instantaneous reserves and short-circuit power.

Übersichtsgrafik mit Themenschwerpunkten

With the beginning of the energy transition, there is a trend towards decentralized energy resources (DERs), primarily based on wind and solar energy. Additionally, new types of hybrid loads are becoming increasingly common, e.g. electric storage devices and charging infrastructure for electric mobility concepts. All these loads should be taken into account both when planning future networks and operating the current energy supply system

Projects

  • Neutral point treatment in distribution grids under consideration of harmonics
  • Contributions of DERs to the provision of ancillary services
  • Assessment of controller stability in DER-dominated distribution grids
  • Cellular grid operation and its requirements
  • Sustainable energy systems - interdependence of technical design and social acceptance
  • Novel concepts for the operation of electrical networks through decoupling via power electronics
  • Methods of network reduction while maintaining system-relevant characteristics of DEAs
  • Stochastic bottom-up modelling of low-voltage grid loads taking into account future user behavior
  • Conversion of existing AC cable sections to DC connections
