Reproducible Example

>>> pandapower.rundcpp(topo)
 RuntimeWarning: invalid value encountered in divide
  V0[gbus] = gen[on, VG] / abs(V0[gbus]) * V0[gbus]

I tried only DC run pp and I have this runtime warning, all the attributes seems ok, DC powerflow should provide better warnings in irder to find where the error is

Issue Description and Traceback

The slack is already set and the balance looks good, atleast DC load flow should work.

Expected Behavior

DC loadflow should work or the exception should be more descriptive

Installed Versions

python version: pandas version: networkx version: scipy version: numpy version: packaging version: tqdm version: deepdiff version: Operating System name/version: python 3,11 pandapower 2.14.6 pandas 2.2.1
