Problem Description

I am writing a pipeline that converts large DataFrames to a large pandapower network. I estimate the size of the DataFrame containing switch data to be over 50,000 rows. Simply running the create_switches function with this DataFrame takes 10-20 minutes, whereas functions like create_lines take less than a minute with a similar sized DataFrame.

I understand this is caused because it is checking if the bus and element matches the element type and is a valid bus. In my situation, I would prefer to have this function run in less than a minute than being sure the busses are valid.

def create_switches(net, buses, elements, et, closed=True, type=None, name=None, index=None,
                    z_ohm=0, in_ka=nan, **kwargs):
    ...
    # This is very slow when len(elements) is very large
    for element, elm_type, bus in zip(elements, et, buses):
        ...
    ...

Feature Description

Perhaps there could be a new flag in create_switches (maybe validate_busses=True), which would determine if the for loop runs or not.

Additional Context

def create_switches(net, buses, elements, et, closed=True, type=None, name=None, index=None,
                    z_ohm=0, in_ka=nan, validate_busses=True, **kwargs):
    ...
    if validate_busses:
        for element, elm_type, bus in zip(elements, et, buses):
            ...
    ...
