1. There is unfortunately no a single function that does comprehensive sanity
checking of the data, though this would be a very welcome contribution.
2. Think of the generator’s voltage setpoint VG as an input to the power flow
problem (it’s an output for the OPF problem). If the generator has sufficient
reactive power capability, that setpoint will generally be maintained, but if
the reactive power limits are enforced ('pf.enforce_q_lims' option), then the
bus voltage at the solution will depart from the generator’s setpoint.
