Hi Jose, Thanks for reminder. I didn’t know this option before. It solved my question. So how do we know which PV bus, is there is any, is converted to PQ bus after using ENFORCE_Q_LIMS option 1 or 2?

(see Table C-2 in the manual) Also, be aware that options 1 and 2 may yield different solutions, in general. -- Jose L.

Some even exceed the negative limits. The thing is the reactive power demand of the load and system isn’t large. Can you see what might be wrong? Blessings, Wenlei
