Presentation: Arjan Wargers (ElaadNL) and Rolf Bienert (OpenADR)
If you want to deploy flexible charging of electric cars for grid management you need a working communication chain. Messages must travel form grid operator or energy supplier to EV-charging stations or Home Energy Management Systems (HEMS) to adjust the speed or timing of charging. A communication standard, Open ADR, could be the missing link! But what is it, how does it work and and why was it chosen in the Netherlands to control public charging stations for grid management and congestion prevention?
This presentation is a brief introduction in this for many not yet well known protocol that will soon be crucial in the roll out of smart and grid aware charging
OpenADR stands for Open Automated Demand Response and is an internationally recognized communications standard for automating demand response (DR) in the electricity grid. It provides a standardized, open, secure, and two-way communication model that allows energy companies, grid operators, and customers to exchange dynamic price and reliability signals. This enables energy users, such as those in electric vehicle charging networks, to automatically adjust their energy consumption based on real-time grid information, improving grid efficiency and helping to balance supply and demand.
