Consider the following 11-bus, full-topology model. Given the breaker statuses, this system would contain 4 superbuses shown in the next figure.
We apply consolidation to the system above considering that the primary buses of each superbus are buses 1, 4, 7 and 10. The system topology at this point (which is never seen by the user) would looks as follows.
At this consolidated state, the breakers and the non primary bus buses could be removed without affecting the power flow solution.
