Spatial scaling behaviour of an optimized highly renewable European electricity system — •Jonas Hörsch, Tom Brown, and Stefan Schramm — Frankfurt Institute for Advanced Studies (FIAS), Goethe-Universität, 60438 Frankfurt am Main, Germany

Techno-Economic investment planning of electrical energy systems is mostly based on optimizing large-scale spatial Linear Programming (LP) problems that find the spatial distribution of generation and transmission capacities for minimal capital and operating costs. The tractable spatial resolution of this type of problem is strongly limited by computational complexity, so that many studies of renewable energy integration have reduced the network to representative nodes with as few as one node per country. In this study a clustering algorithm is used to reduce the number of nodes and lines of a high resolution network-solution while preserving the most important transmission corridors. Preliminary results are presented that quantify the effects of the spatial scale on the operation of the electrical network and the threshold to a necessary scale invariance of the energy flows.
