To communicate to MATPOWER to exchange network data these functions are available.

pandapower.converter.from_mpc(mpc_file, f_hz=50, casename_mpc_file='mpc', validate_conversion=False, **kwargs)

This function converts a matpower case file version 2 to a pandapower net.

Note: If ‘mpc_file’ ends with ‘.m’ the python package ‘matpowercaseframes’ is used. If ‘mpc_file’ ends with ‘.mat’ ‘’ is used. Other file endings are not supported. In that other cases, please, rename the file ending or use the internal subfunctions.

Note: python is 0-based while Matlab is 1-based.


mpc_file - path to a matpower case file (.mat format not .m script).


f_hz (int, 50) - The frequency of the network.

casename_mpc_file (str, ‘mpc’) - The name of the variable in .mat file which contain the matpower case structure, i.e. the arrays “gen”, “branch” and “bus”.

**kwargs - key word arguments for from_ppc()


net - The pandapower network


import pandapower.converter as pc

pp_net1 = cv.from_mpc(‘case9.mat’, f_hz=60) pp_net2 = cv.from_mpc(‘case9.m’, f_hz=60)

pandapower.converter.to_mpc(net, filename=None, **kwargs)

This function converts a pandapower net to a matpower case files (.mat) version 2. Note: python is 0-based while Matlab is 1-based.


net - The pandapower net.

filename (str, None) - File path + name of the mat file which will be created. If None

the mpc will only be returned

**kwargs - please look at to_ppc() documentation


import pandapower.converter as pc import pandapower.networks as pn net = pn.case9() pc.to_mpc(net, “case9.mat”)
