On 26 and 27 October DTU Electrical Engineering's Center for Electric Power and Energy (CEE) hosted an International Energy Agency workshop on V2X technology with 46 experts from academia, the system operator domain and the car industry attending.
The term “V2X” (vehicle to everything) is used to cover a number of applications where an Electric Vehicle (EV) battery can be used as a power source. This ability strengthens an EVs ability to support the power system since power and energy can be provided instantly from the battery. It also means that the EV owner will have access to electric power where a connection to the power grid is not practical or possible. E.g. craftsmen can charge large power tools while driving between jobs.
During the workshop, CEE together with its partners in the Danish Nikola research project, including NUVVE, University of Delaware, Endesa and Nissan, demonstrated that two series produced electric vehicles (Nissan Leafs) could use V2X to provide frequency regulation. In the demo, that was carried out in the new EVLab facilities – part of the PowerLabDK platform, power was sent back into the power system when the frequency went below 50Hz meaning that there was a demand for power in the electric grid.
This proof-of-concept is important since it shows that thousands of Danish Nissan leafs are already capable of providing advanced V2X-based smart grid services. Ultimately such services should aid the operation of the future Danish power system while reducing the cost-of-ownership for EV owners.
The International Energy Agency (IEA) has created a task to investigate V2X as it is seen as one of the key technologies that will help the EV to realize its potential in a smart grid context.
