Elli and MITNETZ STROM publish concept for smart grid integration of EVs

Smart grid integration to increase the share of the green power grid and relieve local grids

Elli, a brand of the Volkswagen Group, and MITNETZ STROM have now launched the nationwide pilot project for smart grid integration of electric vehicles. In the first step, about 20 drivers of Volkswagen models ID.302ID.403 or ID.504 are working to make electric cars part of the energy system in the future and to increasingly use green energy from the region for charging.

With the concept “Innovation Impulse for Future-Proof Grid Integration of E-Mobility”, the two project partners, together with E-Bridge, are now presenting the centerpiece of this field test at E-World (June 21-23) in Essen, Germany. There they provide a first insight into what a practical implementation of smart charging could look like.

The idea behind it: An algorithm uses price incentives to compare car charging plans with regional electricity production from renewable energy sources and available capacities in the distribution grid. The resulting flexible grid use is intended to reduce the frequency of bottlenecks in the electricity grid and create financial benefits for participants.

“With this project, we show for the first time how electric cars can be synchronized with the electricity grid in a user-friendly way. The car becomes a mobile electricity storage facility for the grid operator. For drivers, financial added value is generated through price incentives,” says Niklas Schirmer, Vice

Chairman Strategy Elli. “By making the electricity demand of EVs more flexible, more renewable, regionally generated electricity can be used.” In 2020 alone, some 6,200 GWh of green electricity had to be cut in Germany.

“Together we support the energy and transport transition locally and we invest in the energy future. E-mobility and the energy industry go hand in hand here. EVs can run on green energy and relieve the burden on the electricity grid where it is particularly necessary. We can prevent bottlenecks in the local grid by allocating charging processes for electric vehicles to the available grid capacities using newly developed software. The concept now gives us important insights into whether our approach is customer-friendly,” adds Dr. Michael Lehmann, Head of Process and Systems Management at MITNETZ STROM.

The results of the pilot test are expected in the autumn of 2022. More information and the concept to download are available at www.smartes-laden.eu.
