Hello Shri Thanks for getting back.
I'd like to make my situation more clear. My work involves scaling up the all the loads in a power network in an incremental fashion up until the power flow equations become unfeasible. So I progressively stress the system by increasing all the loads through a load multiplier factor, lets call it mu. As I do this, the system will not converge for some value of mu, in case of 39 bus system, mu=1.239, which means the system collapses when all loads are scaled up by a factor of 1.239 Now I'd like to plot the nose curve (FULL) of any arbitrary bus using the CPF in MATPOWER. So ideally what I want is bus voltage plotted with mu. Can i get additional insights in to how can I modify the default callback function keeping in view my requirements?
