Hi there!
I am using Cornell's matpower 3.0.0 toolbox but I'm confused about
the following:
why is there a flag indicating if the newtonpf has converged
("converged" flag in newtonpf, "success" flag in runpf which I use),
without giving any information if the voltages obtained for each bus
are within the limits? I mean , shouldn't the pflow be characterized
as successful when both convergence and limits are satisfied?
By default, the power flow solver in MATPOWER does not take into
account any voltage limits, branch flow limits or generator limits. It
simply solves the power flow equations. There is also an option
(ENFORCE_Q_LIMS) to respect generator VAr limits by allowing the
voltage to deviate from the setpoint.
I agree that it would be useful to have runpf return information about
whether the solution it found satisfies limits. I will consider adding
this feature to a future version of MATPOWER.
