N2 - The converters in an AC/DC grid form actuated boundaries between the AC and DC subgrids. In both simple linear and balanced dq-frame models, the states on either side of these boundaries are coupled only by control inputs. In this paper, we show how this topological property imparts all AC/DC grids with poset-causal information structures. A practical benefit is that certain decentralized control problems that are hard in general are tractable for poset-causal systems. We also show that special cases like multi-terminal DC grids can have coordinated and leader-follower information structures.
