The majority of distribution grids are not yet designed for the rapid ramp-up of new applications such as heat pumps and private e-charging stations. The distribution grids must therefore be optimised, digitalised and expanded at a rapid pace by the municipal utilities and distribution grid operators.
The instrument of temporary „dimming“ in acute overload situations gives grid operators the opportunity to ensure grid stability even when the number of connections increases. However, preventive control based on calculated overload forecasts is only possible during a transitional period. In addition, control interventions must be reported in detail in a standardised format on a common internet platform to ensure traceability.
EFEN offers a multi-stage concept for smart retrofitting of existing systems. From ready-to-connect pre-wired fuse-switch disconnectors with integrated small signal or current transformers for measuring current network values. Easily retrofittable measured value acquisition modules (MEM) from EFEN are used to integrate network status values via Modbus. The Smart Grid Interface Module (SGIM) offers convenient monitoring and visualisation of grid statuses in local grid stations
