Abstract: 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 will 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 and introduce a stochastic model to quantitatively capture the highly intermittent demand fluctuations.

Abstract: Numerous real-world systems, whether they are of natural or human origin, display complex interactions and dynamics evolving over time. As well known, transforming time series data into a complex network representation helps to gain a deep understanding of the dynamics underlying the data. In this talk, I will provide an introduction about converting time series to complex networks and then introduce a new approach in the context of physics for converting spatial-temporal series data into a complex network. And as an example study, I will discuss its application to the air quality of various regions in Istanbul, the largest metropolitan city in Turkey with a population of approximately 16 million.
