The German demonstrator aims to use the flexibilities connected to the low-voltage grid for congestion management and voltage regulation. For this purpose, flexibilities are provided via an aggregator and offered on a market platform to make use of flexible resources. The aggregator supports customers in making their flexibility solutions available by virtually combining the individual units.
The system operator can then fall back on these capacities in the event of predicted grid congestion. Basis for the correct selection and integration of flexibility solutions are the UMEI standard and grid tools which are developed in the EUniversal project. In supplement, remaining flexibilities in the low-voltage grid are aggregated in the local substation in order to be able to eliminate congestions in the upstream medium-voltage grid as well.
