The voltage angle is considered to be a variable at all buses except the
reference bus. So you can change the specified voltage angle at the reference
bus(es) manually, or you could use the extended OPF formulation (see Sections
6.3 and 7 in the MATPOWER User’s Manual
<http://www.pserc.cornell.edu/matpower/docs/MATPOWER-manual-6.0.pdf>) to apply
constraints or costs to voltage angles.
