a. The short answer is “no." See the last paragraph in section 4.1 of the MATPOWER User’s Manual <http://www.pserc.cornell.edu/matpower/docs/MATPOWER-manual-7.0b1.pdf>. b. I’m not an expert on transformer modeling, so I’m not sure if you can included the magnetizing conductance in the model in Fig. 3-1. c. See the answer to a.
