runpf does not enforce any line limits. You need to run optimal power flow (runopf).

Other two rates are of no use. I am trying to make a line congested by limiting its limit. here is my following case- define_constants; mpc=loadcase(case30) mpc.branch(:,RATE_A)=10; results=runpf(mpc); I firstly i run the above code without limiting the rate and then after limiting the rate, but the power loss is not changing at all in any of the cases.. help me out. thanks in advance.:)
