Net load variability in the Nordic countries with a highly or fully renewable power system

Increasing the share of intermittent renewable energy (IRE) resources such as solar, wind, wave and tidal energy in a power system poses a challenge in terms of increased net load variability. Fully renewable power systems have been analysed in recent studies. Here, we investigate how the net load fluctuations in the Nordic power system are affected by the injection of different combinations of IRE and whether a wise combination of resources can reduce the total variability. We show that the optimal mix of IRE is dependent on the frequency-band considered. Long-term (T>4 months) and short-term (T<2 days) fluctuations can be similar to today’s even for a fully renewable system. Fluctuations with periods in between will however inevitably increase significantly. This study indicates that, from a variability point of view, a fossil and nuclear free Nordic power system is feasible if properly balanced by hydropower.
