Generic Coordinates

If there are no geocoordinates in a network, generic coordinates can be created. There are two possibilities:

1. igraph (http:/igraph.org/python) (recommended) based on

   • python-igraph
   • pycairo

2. graphviz (http:/www.graphviz.org) based on

   • networkx
   • graphviz

Two avoid having two compile C libraries, precompiled wheels are available on https://www.lfd.uci.edu/%7Egohlke/pythonlibs/ (unofficial)

Generically created geocoordinates can then be plotted in the same way as real geocoordinates.

pandapower.plotting.create_generic_coordinates(net, mg=None, library='igraph', respect_switches=False)

This function will add arbitrary geo-coordinates for all buses based on an analysis of branches and rings. It will remove out of service buses/lines from the net. The coordinates will be created either by igraph or by using networkx library.

INPUT:

net - pandapower network

OPTIONAL:

mg - Existing networkx multigraph, if available. Convenience to save computation time.

library - “igraph” to use igraph package or “networkx” to use networkx package

OUTPUT:

net - pandapower network with added geo coordinates for the buses

EXAMPLE:

net = create_generic_coordinates(net)

Example plot with mv_oberrhein network from the pandapower.networks package as geographical plan (respect_switches=False):
