The new platform enables local parts of the grid to disconnect from the central grid and self-heal.

CSGriP divides the central grid into many small cells to function autonomously. These local cells take over control in case of a central grid power outage

The cells will automatically start restoring all local sources of energy supply such as solar and wind, allowing to distribute the energy to local consumers.

CSGriP will automatically reconnect to other cells when the grid balance within a cell is restored.

The new solution is being tested at the Application Centre for Renewable Resources (ACRRES) in Lelystad, the Netherlands. It aggregates local energy sources with local energy consumers.

Developed by Alfen, the 0.5MW energy storage system complex algorithm will be used for local energy management.

Other project partners include the Delft University of Technology, Application Centre for Renewable Resources, HAN University of Applied Sciences, Avans University, Bredenoord, DNVGL and grid operator Alliander.

Alfen energy storage specialist Evert Raaijen said: "Unique about this solution is that the local cells are intrinsically stable through self-adjustment of supply and demand based on the frequency of the electricity grid.

“This makes the grid truly self-healing in cases of central grid outages. The self-healing mechanism based on frequencies truly sets it apart from many IT-related smart grids that require relatively vulnerable data and ICT connections for balancing local grids."
