Re: Performing N-1 contingency analysis

[Jose Luis Marín]

I'm attaching a structured script I wrote some time ago for carrying out
N-1 contingency analysis. You may use it as a guide, but I'm sure you will
need to make changes in order to adapt it to your specific needs (in
particular, the metrics I compute were very specific of the analysis I was
doing).  I only included branches, but it's easy to include other elements.

As Ray said, you've got to be careful with islanding (also beware of
possible changes in the swing bus, because of that).

MATPOWER does not automatically handle contingency analysis, so you will have 
to handle it yourself by removing generators and branches from the network one 
at a time by setting GEN_STATUS and BR_STATUS to zero. Keep in mind that you 
can create islands or isolated buses by taking branches out of service. The 
case_info() 
 
and find_islands() 

 can helpful with detecting such cases.
