Dear all,
Hi. I have a question about the OPF problem modelled in the MAFPOWER package. I
know that if we just define the generator active power cost curve data in the
gencost matrix and leave the generator reactive power cost curve data related
fields empty, the objective function of the OPF problem would be reducing the
generators active power cost in the system. What I can't figure out is that
what forces the generators reactive powers and bus voltages values to be
derived as same values when we run the OPF problem again and again on the same
system. As you know, when the objective function is to reduce the generators
active power cost, controllers like generators reactive power or bus voltages
have negligibe impact in the solution. So, is it possible to have one set of
generator active powers and various sets of generators reactive power and bus
voltages as the final solution of the OPF problem when we run it again and
again on the same system? Your explanation regarding my question would be much
appreciated.
Kind regards
