Hi all,

Is there some API function that does the same thing as Summation label does in the GUI?

I have Summation label for ac branch flow (that works): "LF,+,1000 2000 1 F" and "LF,+,3000 4040 1 F"

I want to plot the same ac branch flow in Python in dynamic simulation. I have the "POWR 1000 TO 2000 CKT '1 '" from using psspy.chsb, which is the same as "LF,+,1000 2000 1 F" if I understand correctly.

However, I don't have the same for "LF,+,3000 4040 1 F", that is, I don't have "POWR 3000 TO 4040 CKT '1 '", which is why I want to find out if there is API function that does the same as The Summation Label.

Thanks!!
