So, are you attempting to run MATPOWER’s OPF using the MIPS solver? Or are you
trying to set up your own OPF problem and use MIPS to solve it?
If it’s the first, then you don’t need to worry about any of the internals,
just call runopf() with the the ‘opf.ac.solver’ option set to ‘MIPS’. If it’s
the latter, then dh is mandatory for problems that include nonlinear
inequalities. For an example of how to compute the gradient for the OPF, just
look at MATPOWER’s implementation in opf_consfcn.m.
