Honda BEV fleet ready for V2G
As part of a pilot project with Next Kraftwerke GmbH, one of the largest operators of virtual power plants (VPP) in Europe, the Japanese have achieved certification for the prequalification of primary control reserves (PCR) by Amprion GmbH in Germany. Amprion GmbH, based in Dortmund, is a German transmission system operator. The company operates the second largest high-voltage power grid in Germany, with a circuit length of nearly 11,000 km. It extends over seven western German states.
Grid Stabilization through BEVs
In the event of short-term frequency deviations in the power grid, operators use balancing services that automatically compensate for imbalances between supply and demand. The PRL is the highest performance class among these balancing services for grid stabilization. It is also referred to as the primary control reserve, as it is the first response to frequency disturbances.
In the pilot project, mass-produced Honda e electric vehicles were used to provide PRL services for the transmission system operator (TSO), thereby qualifying to support grid stability. In addition to the six Honda e, six Honda Power Managers were also used in the project. These are bidirectional CCS chargers. Honda was able to meet the high requirements for charging and discharging necessary to ensure a stable 50 Hz grid frequency.
Communication with the Grid in Real Time
The Honda power management system uses real-time information on the current power capacity from Next Kraftwerke and is able to respond to the charging and discharging requirements of the TSO for each individual vehicle within the required standard time, while taking into account the individual preferences of respective EV drivers regarding the state of charge. This development is an important step towards strengthening the role of EVs and bidirectional charging technology in a future sustainable energy system. In addition to further expanding renewable energies, maintaining consistent grid stability will pose one of the biggest challenges for TSOs.
"The project with Next Kraftwerke allows Honda to meet the new requirements of the European market and develop technologies that provide added value to society," said Tom Gardner, Senior Vice President, Honda Motor Europe. "Electric vehicles are connected to charging stations most of the day, whether at work or at home. Honda believes that these idle times can be used to offer additional services and revenue streams through smart charging and discharging based on the current grid frequency. This benefits not only electric vehicle owners but also the infrastructure on the path to a society shaped by electromobility."
What does this mean?
More and more electric vehicle manufacturers are demonstrating their capabilities in V2G. Now it is up to grid operators and policymakers to exploit the potential of BEVs for stabilizing the power grid.
