Dear Prof.Zimmerman, Thank you for your reply, my understanding to this
quesion is the same as your reply, but when I get the results of rundcopf('
case24_ieee_rts') after setting branch(21,6)=230; branch(30,6)=180(In order to
simulate the situation of reaching the bound of flow constrains.), it shows
that most of the MU_SF and MU_ST of the same branch is non-zero at the same
time instead of only one of them is non-zero. So can you explain this situation
to me? Thank you!
sincerely yours,
Hu Yuan
