What I would recommend is making a slight modification to newtonpf.m <http://www.pserc.cornell.edu/matpower/docs/ref/matpower6.0/newtonpf.html>, where you insert at line 102 a call to a function defined by you, to which you pass the complex bus voltage vector V and anything else you need (e.g. Ybus, Sbus, etc.). Inside that function you do whatever you need to to interface with OpenDSS.
