Voltages and impedances are specified in p.u. in the case file data, but powers in MW and MVAr. That is, the conversion done internally, is simply to divide all of the powers by the baseMVA.
If you were to specify the powers in p.u. and set the baseMVA to 1, you should get the same solution, with the solution powers also expressed in per-unit, of course. Internally, it would be solving everything with the same values.
