Dears,
I‘m trying to calculate power flow in distribution systems considering network reconfiguration. From the data format description, I noticed that the 11th column of mpc.branch named BR_STATUS represents "initial branch status". But I'm not sure whether that attribute means the on/off status of branches and thus determines the network topology. Take 'case33bw' as an example, when I was trying to change the 11th column of mpc.branch (network connectivity and radiality is guaranteed) and execute runpf, the power flow calculation fails to converge in some network topology (success=0 and it reaches max iterations). I have tried several power flow algorithms as well as increase the max number of iterations, but all fails. So the question I'm gonna ask is: 1) While doing power flow calculation, does BR_STATUS determine the network topology? 2) Any suggestions for cases where power flow cannot converge? Thank you in advance, early reply is appreciated. Regards, Yan
