Should I expect a convergent and (reasonably) accurate power flow solution, when I experiment with changing the bus type PQ->PV and vice versa?
If so, is there a minimum number of each bus type required, e.g. consider a system where there are only PQ buses (apart from one slack, of course)? The data in the test cases seems sufficient for such changes, however I'm worried about the stability of the system of equations. Thanks a lot
