Why python do not recognise _i ?
psspy.bus_data_2(12000,[1,3,_i,_i],[220.0, vpu,angle],"B1")
when I hardcode the script to a fix value below, it works
psspy.bus_data_2(12000,[1,3,1,1],[220.0, vpu,angle],"B1")
The reason I would like to get around this is so that I don’t have to specify the values that are considered default values.
the _i is a special variable that PSSE adds to the Python environment when you are running scripts from inside PSSE. Here is a list of the other special variables:
_i, _f, _s and _o
It is confusing to me why this variable is added without needing to import it.
When running your Python from outside of PSSE, you'll need to import the _i.
from psspy import _i
Otherwise your program will stop with a NameError which means: Python cannot find where this variable has been defined.
