Dear Matpower community,
I have a system with one load bus faulted to ground (v=0). The system with
normal operation works fine. The system with the fault, however, cannot be
solved owing to low voltage problem. I tried to deal the faulted load bus as a
generator bus with V=0. I converted all loads from constant powers to constant
impedances as suggested by Shri in this group in my previous question. The
system still cannot be solved. Is there any idea to get around this problem?
Thanks in advance
Ismael
Ismael: The methods that are generally used to analyze a fault have
major differences with respect to the assumptions of the classical power
flow problem. A normal power flow solution algorithm can be expected to
fail on a network with a fault. A good classical reference for this is
"Analysis of Faulted Power Systems" by Anderson.
