Almost ... in a conventional power flow, the power injection and the voltage magnitude at each generator bus is specified. In the OPF it both are only constrained by upper and lower bounds. You could set the bounds to your specified PG and VG values if you wanted, then it would be what you describe. -- Ray Zimmerman Senior Research Associate 211 Warren Hall, Cornell University, Ithaca, NY 14853 phone: (607) 255-9645
