Principal Components of the European Power System — •Fabian Hofmann, Jonas Hoersch, and Stefan Schramm — Frankfurt Institute for Advanced Studies, Frankfurt, Germany

The European power system represents a huge network of different nodes, each with a complex time-dependent behaviour. In order to efficiently integrate renewable energy sources, such as wind and solar, it is a major task to understand and handle their additional effects. In particular, the more renewables in the system, the more the power generation will be subject to the weather. We therefore build up a european power system, which is dominated by non-conventional power generators, and extract general time-dependant patterns from it by applying a Principal Component Analysis to the timeseries of the nodes. This reduces the multivariate dimension of the system to a small number of general patterns, which are though uncorrelated but may not necessarily be statistically independent. Furthermore, these dominating patterns determine main flows in the network and can be used to align investments and network design.
