Clustering Dataset

This dataset contains jointly optimised energy system model networks on
transmission and generation level with the objective to minimise total
system costs under the constraint to reduce 95% of CO2 emissions
compared to 1990 by a greenfield approach. We vary the spatial
resolution on different scales (clustering on generation sites, the
transmission network and joint clustering) to research the impact of
each scale separately for the optimisation process. For each resolution,
we additionally consider seven different transmission line expansion
volumes. Results indicate, that in the current European transmission
system, transmission network bottlenecks play a more restricting role
than resource availability. Accounting for bottlenecks can raise total
system costs by up to 19%, while a higher resource availability
(locations with higher capacity factors) mitigates the increase only by
6.5%. Both cases result in strong differences in the composition of
technology investments.

A detailed survey of the results will be presented in the paper "The
strong effect of network resolution on electricity system models with
high shares of wind and solar".
