Asymmetric /Three Phase Power Flow
==================================

pandapower uses Sequence Frame to solve three phase power flow :

.. autofunction:: pandapower.pf.runpp_3ph.runpp_3ph

.. note::

    If you are interested in the pypower casefile that pandapower is using for power flow internally, you can find it in net["_ppc0"],net["_ppc1"], net["_ppc2"].
    However all necessary information is written into the pandapower format net, so the pandapower user should not usually have to deal with pypower.

    For transformers, shift is reversed in negative sequence.


Asymmetric Power Flow using power-grid-model
--------------------------------------------

The same function mentioned in :ref:`Balanced AC Power Flow using power-grid-model <pgmpowerflow>`, ie. `pandapower.run.runpp_pgm()` can be used for asymmetric power flow calculation.
The argument `symmetric=False` should be set for this purpose.
