Reliable functioning of infrastructure networks is essential for our modern society. Cascading failures are the cause of most large-scale network outages while small fluctuations dominate the grid on a daily basis. In this talk, we demonstrate the importance of transient dynamics when investigating cascades in power grids. Furthermore, we analyze power grid frequency fluctuations based on measurements from several continents, explaining heavy tails and revealing the impact of trading.
