Query: Distributed AC-DC Optimal Power Flow in the European Transmission Grid
  with ADMM   Distributed or multi-area optimal power flow appears to be promising in order
to cope with computational burdens in large-scale grids and without the
regional system operators losing control over their respective areas. However,
algorithms are usually tested either in small test cases or single countries.
We present a realistic case study in the interconnected European transmission
grid with over 5000 buses and 315 GW load. The grid is partitioned into 24
areas which correspond to the respective single countries. We use a full
alternating current model and integrate multi-terminal direct current systems.
The decomposed problem is solved via a modified Alternating Direction of
Multipliers Method (ADMM), in which the single countries only exchange border
node information with each neighbor. In terms of generation costs, the solution
of the distributed optimal power flow problem deviates only 0.02% from a
centrally computed one. Consensus between all regions is reached before 200
iterations, which is remarkable in such a large system.
