Mirish,
Before moving further, I would suggest you to review the practicality of
the assumptions you are making.
1) Does it make sense to move the loads, generation to a higher voltage level?
2) For a utility engineer working on a real system, would he/she add dummy
branches to make the analysis converge/feasible?
I don't much about the problem you are trying to solve, but I feel, based on
the description below, that you should first define the problem clearly with a
set of assumptions conforming reality.
