Researchers test advantages of DC power grids

In the context of the energy transition, DC technology is becoming increasingly important, as it offers a number of advantages in energy distribution over conventional AC grids. It simplifies a number of tasks that require additional effort if implemented with AC – for example the coupling of distribution networks or the supply of quick charging points for electric vehicles. In contrast to AC networks, DC networks are also suitable for the necessary flexible, bidirectional energy flow between generators and consumers under the requirements of the energy transition since they are much more resilient when energy is fed in simultaneously at many points. Plus, they are easier to control.

The test network at the research campus FEN will be set up with a voltage of 5 KV, have an installed capacity of around 6.2 MW and a total length of approximately 2.3 km. In the final expansion stage, five stations will be connected, some of which operate both as consumers and feeders. Energy storage and renewable energy soruces will also be integrated. The grid is scheduled to go into test operation at the end of 2018.
