Smart stores for clean mobility and a safe grid

In the future, it will be possible to charge electric vehicles increasingly quickly. The new ultra-fast charging stations supply up to 350 kW of power. This means that a range of 100 km can be charged in only five minutes. What delights car drivers comes with huge challenges for the power grid. With increasing charge power for the newest generation of electric vehicles, grid connection outputs of up to 1 MW will be needed for e-mobility charging hubs. The SYNERG-E project takes up these challenges and the associated high system costs for the installation and operation of high-power charging infrastructure for electromobility and develops new solutions.

Local buffer stores ensure mobility and network stability

The main task of the energy power packs is to take the strain off the electricity grid through “peak shaving”. When electric cars charge at ultra-fast charging points capable of delivering up to 350 kW, then a portion of the energy and power required can be immediately drawn from the battery. This ensures that the grid is not put under too much strain and network charges remain reasonable. At times when the charging station is not being used, the buffers are recharged with 100% renewable electricity from VERBUND and their flexibility used for grid services such as balancing energy. 

First battery store for use on the balancing energy market

The battery stores at the distribution points in Wien Favoriten, in Feldkirchen near Graz and in Innsbruck are the first pre-qualified battery stores for the balancing energy market in Austria. The two battery stores in Bergkirchen and Heppenheim will also be pre-qualified and are intended for use on the balancing energy market in Germany. Additionally, the flexibilities of the batteries can also be used for the intraday market. Thanks to intelligent optimisation and swarm control via Volery, a digital optimisation platform of VERBUND Energy4Business GmbH, the batteries will be charged at the most favourable times of day and marketed on the energy market.

Tailored control

The smart controlling and monitoring of all system components such as battery, charging station and grid connection is performed by the “Smart Grid Management System”. The system tailored by the VERBUND Energy4Business team ensures that all components communicate and function optimally with each other. A major advantage of this “home-made” solution is that the requirements for the controller are precisely defined, which means they can be adapted for other applications in the area of industry and mobility with relatively little effort.
