Hello sir,
I have commented all the tie lines and then trying to run the radial pf
using the following commands-
mpopt=mpoption('pf.alg','PQSUM','pf.tol',1e-4,'out.all', 0,'verbose',0);
mpc=loadcase(case33bw);
results=radial_pf(mpc,mpopt);Number of detected loops: 1 Error using radial_pf (line 34) radial_pf: power flow algorithm PQSUM can only handle radial networks. It is still not running sir.
