Fast Frequency Support Impact On Nuclear Generation

| 2025:1145 | Danilo Obradovic', RISE
This project assessed how Fast Frequency Support (FFS) from an HVDC link interacts with nuclear-type synchronous generator dynamics.
2025-1145

A Nordic-based test case was modelled, and droop-based and synthetic inertia FFS studied. Simulations across varied scenarios show that FFS can enhance the system stability when appropriately implemented, though certain edge cases reveal risks if control coordination is poor.
