a. radians b. In both of those cases, there are no constrained branches (i.e. all mpc.branch(:, RATE) are zero), meaning there are no branch flow limits to evaluate, so opf_branch_flow_fcn() does not need to be called.
c. A function pointer to opf_branch_flow_fcn() is declared with the input parameter il in line 320 of opf_setup.m<https://github.com/MATPOWER/matpower/blob/a6a489c3d3a83f5c65fc7e0a5dc5306eb7cc6ac0/lib/opf_setup.m#L320>, and il is defined in line 287<https://github.com/MATPOWER/matpower/blob/a6a489c3d3a83f5c65fc7e0a5dc5306eb7cc6ac0/lib/opf_setup.m#L287>.

What is the unit of voltage angle 'Va' within opf_branch_flow_fcn.m , degree or radian? b. While running opf for some of the cases like case14, case118, etc. when I set the breakpoint within the opf_branch_flow_fcn.m, it does not halt there; what are the reasons for that? Though for cases like case9 or case5, it does enter in the branch_flow_fcn code? c. where the 'il' (an input to opf_branch_flow_fcn) is first declared? and which one is the immediate code before opf_branch_flow_fcn where 'il' has been modified?
