Power system restoration in MATLAB (Graph Theory)

I have to solve restoration service problem in distribution network system in MATLAB using graph theory by optimization method. Did anyone do anything similar to help me by giving some guidelines or instructions? Precisely, I need to find all possible ways for power supplying an area after the failure.

Typically, you'll get more responses if you show us what you've got so far.
