The regulation ensures grid stability and safety through several mandates:
This standard is mandatory in Germany for all new generation systems connected to the low-voltage network. It ensures grid stability, personnel safety, and standardization of grid integration.
: Generators must adjust their power output based on grid frequency (e.g., reducing output if the frequency is too high) to prevent grid collapse.
The VDE-AR-N 4105 standard is published by the German Association of Electrical Engineers (VDE), a renowned organization that develops and publishes technical standards for electrical engineering. The standard provides detailed specifications for electrical installations, including planning, design, and execution. It covers a wide range of topics, such as electrical circuit design, protective measures, earthing systems, and testing procedures.
VDE-AR-N 4105 is the German technical connection rule for power generation systems (like solar PV or battery storage) connected to the distribution network . It ensures that small-scale energy systems support grid stability rather than disrupting it.
: Requirements for reducing power during over-frequency events. Network and System (NA) Protection
