LG Electronics has developed an app to accurately forecast when the vehicles will be at the charging station and thus available for control reserve. Hyundai employees enter the charging times of the EVs into the app. In addition, LG Electronics and Hyundai Motor Group developed a cloud-based platform that pre-aggregates the assets as a sub-pool and coordinates the provision of balancing power. Charging or discharging of the vehicle storage in the event of a control energy activation is controlled by a bidirectional charging station connected to a gateway. On a household level, Wallboxes and LG ESS home 10 storage units will complement the sub-pool. The wallboxes and home storages have already proven that they can technically fulfil the prequalification.
With this project, Next Kraftwerke is continuing its efforts to contribute to the stabilization of the power grid with the flexibility of smaller assets. In terms of its versatile benefits, the project is a first. "In collaboration with our cooperation partners, we have prequalified a fleet of vehicles from Hyundai Motor Group for secondary control reserve, which has the highest technical requirements of all control reserve products. It has been proven that it is possible to provide balancing power from electric vehicles without restricting the usability of the vehicle," says Alexander Krautz, Head of Business Development at Next Kraftwerke.
Based on the proven concept, additional locations and larger vehicle fleets can be easily and cost-effectively integrated into the pool. Hyundai Motor Group also expects the project to help its V2G technology contribute to a greener society as EVs become a means to overcome grid instability as new and renewable energy becomes more commonplace. The initiative will also maximize benefits to EV customers by reducing the total cost of ownership (TCO).
