Real gains from flow-based methods for allocating power transmission capacity in Europe
Résumé
This paper aims at understanding and assessing the main methods proposed by ETSO and EuroPEX [1] to define and allocate interconnection capacities in Europe. We model these methods and evaluate their technical and economic efficiency on a 7-node network. We find first, that, unsurprisingly, the allocation methods are all the more efficient as the Kirchhoff laws are integrated more precisely in the market clearing. Second, and more surprisingly, we find that the zonal vision of the grid considered by all these methods has important consequences on the technical and economic efficiency as it may cause the capacity limits of powerlines to be exceeded.
