Re: Hello! Need Advice Guidance
I didn’t get a chance to look at your code carefully, but is there a reason you
are not simply using the continuation power flow (see chapter 5 in the manual
http://www.pserc.cornell.edu/matpower/manual.pdf) in MATPOWER?

RTS-96 Test System in matpower format
Hi, i would like to ask if someone has RTS-96 Test System in matpower format. A link http://www.parallelcoding.com/wp-content/uploads/Research/MCSPruning/case96.m that is suggested in a previous conversation is not working. Thanks in advance for your interest! --- This email has been checked for viruses by Avast antivirus software. http://www.avast.com
Re: Hello! Need Advice Guidance
Hello Ray,
Thank you for your response. I realize about the CPF method but I and
specifically trying sensitivity analysis using PV Curves. Hence seeking for an
advice.
Thanks Regards,
Sridevi
