Thank you so much. The second scenario I had talked about it is: (it is a general question but I want to implement it MATPOWER):
In MATPOWER, in transmission grid, we say that changing system states acquired after state estimation can lead to a change in active and reactive power since estimated states are used to recalculate some parameters. Now, in this case file "case33bw" which is for the distribution network, I want to know if I change the obtained voltage magnitude and angle of runpf(), what will happen and what parameters will be affected. How can I use MATPOWER to know that?
