Fig. 4From: A comparison of clustering methods for the spatial reduction of renewable electricity optimisation models of EuropeResulting regions respective clustering method at a resolution of 67 nodes. The color-map reflects the annual capacity factors for all the methods, except for \(f^\mathrm {time}(v)\), where it is the average capacity factor of the time-series at 8 o’clock in the moring. Original regions/nodes are highlighted by white boundaries of respective voronoi regionsBack to article page
