If you are referring to the mechanism described in Section 6.5.2 in
the User's Manual <http://www.pserc.cornell.edu/matpower/manual.pdf>,
then yes. In that context, each interface is defined in terms of a
specific set of branches, so you could define it only in terms of the
direct links between areas 1 and 2.

Thank you for your answer. Let me ask you one small question.
Assume that we have 2 areas and links between them and area 3.
Power, from area 1 to area 2, can flow :
1. directly through branches that belong to interface area1-area2.
2. through area3(from area1->area3->area2).
Is there any way to consider first transfer throw direct links and
skip transfer through area3 ?

Aneta

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.

question, why this is done as DC (not AC) ?
(Because of computational cost or implementation complexity ?)

Dear all,
I have a question regarding the max P constraints
of the group of branches.
Are there easy way to set up constraints for
group of links
For example***
* case9Q branch 5-4 PF+branch 5-4 PF <
assumed Const
Best regards,
