Dear Professor Zimmerman:
I have an inquiry with regards to power flow simulation (runpf). Im using 1671 buses for my network data. I tried running power flow. Unfortunately, after I made the command, most of the PV buses were converted to PQ buses because Q limits were reached and consequently my reference bus was changed to PQ bus. Thus, matlab showed the error: ??? Attempted to access pv(1); index out of bounds because numel(pv)=0. Meanwhile, I tried running power flow thru PSSE using the same network data and it converged. Please take note that I converted the network data raw file to a matlab (*.m) input file in order to use matpower. I look forward for your immediate response with regards my concern. Very Respectfully Yours, Manuelito Del Castillo, Jr.
