opt = mpoption('ENFORCE_Q_LIMS', 1);
runpf('case9', opt);
This requires version 3.0.0 or later.

Please tell me where from I can set "ENFORCE_Q_LIMS" parameter to
'1'. I was searching for it, but couldn't get it.
Thank you.

It is not possible to do this directly with the OPF. I'm not sure
if this will accomplish what you want, but first you could run the
OPF with relaxed voltage limits to find the real power dispatch.
Then use that real power dispatch and run a simple power flow with
the desired voltage setpoints and the ENFORCE_Q_LIMS option set to
true. Be aware that this could cause line limits to be violated.

Dear Sir,
I have been trying to fix the voltages of the generator buses
until the generator reactive power limits are reached. However,
when I do this, the OPF simply diverges. I have already relaxed
the line limits as well as voltage limits. The thing I am trying
to do is, fix the voltages of generator buses until the reactive
power limits are reached and if one of the generator hits the
reactive power limits, simply relax the voltage constraints of
that bus and so on. But I am really having problem with this.
Is this modification possible with matpower? If yes, what could be
the easiest way to do this?
I would be very much grateful if you could send me some
suggestions regarding this at the earliest as I have been stuck on
this point.
Looking forward to hearing from you soon.
sincerely
Sarina
