Frequency Stability in Sustainable Power Systems: Effects of Reduced Rotational Inertia on Frequency Stability in the European Transmission System

The large-scale replacement of synchronous generation by non-synchronous PV and wind feed-in will result in reduced rotational inertia in future power systems. Low-inertia operation is charachterised by increased rate-of-change-of-frequency and greater frequency deviations during power imbalance events. In the context of frequency stability, such behaviour is potentially problematic. Using detailed stationary and dynamic models, the degree to which reduced rotational inertia will influence the frequency stability in the future Continental Europe power system is investigated in the presented dissertation.
