If you want to see the effect of changing X on the flow in a line, you will
have to keep everything else constant. So you probably want to just run a power
flow, not an OPF. In your case, there is 180 MW of curtailable load at the end
of a branch with 170 MVA capacity, so the curtailable loads will always be
“dispatched” by an OPF to the capacity of the line.
