I have built an application that simulated an Electricity Grid. More precisely i am simulating the Medium Voltage network only.

I want to be able to simulate a cable fault, where transformers' supply is interrupted. On interruption, the algorithm will re-route supply via an other cable, if availalble. When multiple transformers are interrupted, the algorithm will need to prioritize according to level of priority of a transformer (if feeding an airport or hospital) and that should be restored first.

One constraint i have set to the grid is that supply can only come from one source, thus preserving a radial configuration which would make things simpler.

I was thinking of creating an algorithm that would allow transformers to 'talk' to each other and to connecting cables to check if a current equal to the current required by the transformer can be supplied, that is use a bottom up approach, instead of top-down, from root node
