Sorry, I should have mentioned that the interface constraints were based on DC flow models. This is because the current version of the MATPOWER OPF formulation makes it easy to add linear constraints, whereas adding non-linear constraints would require non-trivial modifications to the code. So it's the latter … implementation complexity.
