Scaling of transmission capacities in coarse-grained renewable electricity networks

摘要: Network models of large-scale electricity systems feature only a limited spatial resolution, either due to lack data or in order reduce the complexity problem with respect numerical calculations. In such cases, both network topology, load and generation patterns below given scale are aggregated into representative nodes. This coarse-graining affects power flows thus resulting transmission needs system. We derive analytical scaling laws for measures capacity cost coarse-grained renewable networks. For measure very weak resolution system is found. The results shown describe infrastructure simplified, but data-driven spatially detailed model European high share fluctuating generation.
