Data-driven load profiles and the complex dynamics of electricity consumption

Power grids are the biggest machines on earth. They are also the most complex ones, as they involve human beings and their complex correlated electricity consumption patterns. In this talk I give some short overview on data-driven research dealing with frequency fluctuations in power grids. Whereas variations in the dynamics of renewable energy generation are reasonably well studied, a deeper understanding of the variations in consumer consumption dynamics is still missing. I will talk about highly resolved residential electricity consumption data of Austrian, German and UK households [1] and introduce a stochastic model to quantitatively capture the highly intermittent demand fluctuations. \\ [1]  M.
