Concept Grid is a real "smart" distribution network representative of a real electric system from the primary substation to residential appliances. This platform offers the possibility to conduct, in a controlled and safe environment, complex testing campaigns which would be impossible to perform on a real network. Its flexible design allows to work in several network configuration to match with the customers’ expectations. The infrastructure also contains existing grid connected storage such as batteries and a water electrolyser platform that can be used to study hybridised storage.
