Storage in Stationary Applications

Energy supply systems are currently undergoing enormous changes worldwide. In recent years, renewable energies have gained in importance. At the same time, electricity generation costs from renewable sources have fallen, so that they are now comparable to those from conventional generation. Concurrently, the transport and heating sectors are becoming increasingly integrated with electricity supply as a result of increasing electrification.

These developments require an increased demand for storage and flexibility options in order to enable a temporal shift of energy and thus secure network operation.

The sharp drop in battery prices in recent years has made it possible to use battery storage as an active element in the energy supply system. On the one hand, this is done by means of battery storage devices of various sizes, which are built for use in the network. On the other hand, this is done, for example, by the secondary use of electric vehicle batteries.

Accordingly, the chair has its own department, which is concerned with the development of operating strategies for PV home storage and grid-connected large storage facilities as well as with energy management systems for large storage facilities and electric vehicle fleets.
