When I try running this code using pandapower to run the powerflow timeseries of a low-voltage system, I get the following error: None of [Int64Index([0, 1, 2], dtype='int64')] are in the [index].
I suppose the problem is due to the csv-files I insert. I have uploaded them according to the correct format and view. Thus first the index of the static generator/load (0, 1 and 2) and then the values of active and reactive power. But even when I add the right index of the static generator/load in the right column, I get this error and I don’t know how to solve this.
Can someone help me with this? The error occured in line 68.

No time steps to calculate are specified. I'll check the datasource of the first controller for avaiable time steps
