Overloading of existing low-voltage local grids due to the increase in new large energy consumers and decentralized generation plants to be integrated is to be expected. The existing distribution and local electricity grids were planned and built on the basis of assumptions that differ from those arising out of the developments in the energy transition. The existing local electricity grids are not designed for the future load and energy demand profiles. This paper presents a conceptual structure that allows for overarching optimization of local grid operation. The owners of the grid connections are brought together on a platform in a local energy community and can use it to coordinate the utilization of the local grid. Coordinated and optimized operations within the neighborhood can reduce energy losses and delay the physical expansion of the grid. Further integration of new producers and consumer systems remains possible losses in the quality of supply. The functional requirements for the concept are identified, existing communication protocols are examined and left open aspects are highlighted.
