The new capabilities included in ACER’s CNC 2.0 recommendations may require updates to some DSOs’ protection schemes. TSO–DSO discussions would be beneficial to collect feedback on how DSOs plan to adapt protection schemes to comply with the new requirements, including – but not limited to – the fault ride-through requirement for Type A generators and grid-forming capability.
The goal is to foster an open discussion on new capabilities and known protection issues in distribution systems, with the aim of ensuring system security and stability. This also includes the schemes and methods for anti-islanding detection to address the new capabilities defined in NC RfG 2.0 and NC DC 2.0 (for electric vehicles and Type A power park modules).
