parameters limits for power flow calculation

[Wu Jun]

Hi all,

>From the case30.m in Matpower, Vmax and Vmin for buses are listed, also the 
>Qmax and Qmin for generators. I want to know how they work during the process 
>of calculating the power flow. If one of them are violated, how does Matpower 
>treat it? Does Matpower keep the original outputs or change the calculation 
>condition automatically then put out a result without breaking any limit?
