Is it possible to predict the operating state of a power system (using MATLAB) if I have calculated the voltages at all nodes by state estimation?

If I have calculated all the node voltages by state estimation, is it possible to predict which operating state my system is at? By operating state, I mean any of the following:

In addition to being able to say which operating state my system is at currently, I want my code to be able to say if there is a risk of heading towards an emergency or 'in extremis' state. I know my question should've been clearer, but I don't know enough at the moment. It would be great if someone could suggest an algorithm and the data I would need to execute the algorithm.
