CIRED 2022 - NORFLEX: ACCOMMODATING E-MOBILITY IN THE DISTRIBUTION GRID. UTILISING A FLEXIBILITY MARKET TO MANAGE GRID CONGESTION
In Norway more than 64% of all new car registrations in 2021 were electric vehicles (EVs). We have investigated the opportunities, challenges, and potential value of E- mobility as part of a flexible energy system. This paper provides insight into how to accommodate E-mobility in the local distribution grid, in addition to functioning as an asset to manage grid congestion and system services with a marked-based approach. The project has developed and tested technology and business models enabling more efficient and sustainable power grid operations. This includes utilising market- based flexibility from the growing number of domestic EV chargers, and hence accommodating E-mobility in the distribution grid. Key to this project in NODES and its innovative approach is an integrated market design that allows for the reservation (LongFlex) and activation (ShortFlex) of local flexibility to be transacted between Flexibility Service Providers (FSPs) and the DSO & TSO. Results from the project show a willingness to implement smart charging, optimised to both hourly energy prices and local explicit flexibility price in NODES. Flexibility volumes have been increasing as FSPs have developed their system to support the new digital value chain and the DSO has automated their processes in GridTools.
