Impact of over-frequency events on Nordic NPPs
This report quantifies over-frequency events by using a simulation model of the Nordic synchronous system and simulating different faults related to the HVDC links, in combination with operating conditions of high and low inertia.

Trends of frequency deviations
In this report grid frequency statistics of the last two decades have been examined together with analysis of inertia values of the Nordic Power System. Interviews have been held with the Nordic Nuclear Production Plant owners and the Swedish and Finnish TSOs. Conclusions are made whether it exist correlations with system quantities like frequency quality, inertia, wind power production, wear and tear of nuclear plants, and system services.
