Backing the creation process
VDE FNN has closely followed the Network Codes creation process and regularly submitted proposals for improvement.
- Requirements do not refer to the grid connection point
- Interfaces between transmission system and distribution system operators
- Frequency-stabilizing measures by the transmission system operator should be carried out in coordination with the distribution system operator
- Definitions must be harmonized and clearly defined (e.g. significant load)
- Demand side response requirements should be reduced to technical requirements
