Specifies how systems must provide reactive current to support voltage during and after grid faults. 3. Protection & Control
The is a technical application rule for the connection of customer installations to the medium-voltage grid (1 kV to 60 kV) in Germany . It was developed to implement the European Network Code "Requirements for Generators" (RfG) at a national level. 📋 Core Purpose VDE-AR-N 4110:2017-02
This standard ensures grid stability and safety as renewable energy sources and storage systems increasingly replace traditional power plants. It defines how systems must behave during normal operation and grid disturbances. 🔍 Key Technical Content 1. Scope & Applicability Specifies how systems must provide reactive current to
Requires "Fault Ride Through" (FRT) capability, meaning systems must stay connected during brief voltage dips or spikes instead of immediately shutting down. It was developed to implement the European Network
Mandatory for systems with a maximum active power (PAmax) ≥ 135 kW. 2. Grid Connection Requirements
Systems must be able to reduce power output via remote control commands from the grid operator.
Defines limits for voltage gradients (< 5% per minute) and frequency gradients (< 0.5% per minute).
