Problem Description

Hey,

I have an ieee 9-bus file with the following cost related data:

%% generator cost data																					
%	1	startup	shutdown	n	x1	y1	...	xn	yn												
%	2	startup	shutdown	n	c(n-1)	...	c0														
mpc.gencost = [																					
	2	1500	0	3	0.11	5	150;														
	2	2000	0	3	0.085	1.2	600;														
	2	3000	0	3	0.1225	1	335;														
	2	0	0	3	0.2	0	0;														
	2	0	0	3	0.05	0	0;														
	2	0	0	3	0.3	0	0;														
];	

Now I get this error:

File "/Users/PaulKandora/opt/anaconda3/envs/copopf/lib/python3.12/site-packages/pandapower/converter/matpower/from_mpc.py", line 100, in _m2ppc
    mpc_frames = CaseFrames(mpc_file)
                 ^^^^^^^^^^^^^^^^^^^^

    raise ValueError(
ValueError: Length mismatch: Expected 6 rows, received array of length 3

I assume that pandapower is unable to detect reactive power costs. Probably, it is possible to detect reactive power costs but I am not sure how.

Grateful for support here and best regards

Paul

@Paulnkk, you are using the matpower sub components? Since we have a quite exhaustive cost approach using polynomial formulation: https://pandapower.readthedocs.io/en/latest/opf/formulation.html#cost-functions it should also support q.
