How would you include currents from load/generation in calculating the bus current?

The task is to determine the continuous current in a bus. I already applied psspy.aflowreal function. However, it only computes the total current in all connected branches in a specified bus. Is there a function that outputs the current injection from a genmachine or current drawn by a load at a specified bus? Thank you!

There is no such API available. You can write your own function that returns the load or machine current calculated from the MVA load and the bus voltage.


As an example, I wrote a script that plots the complex currents in a vector plot. See example below for bus 201 in savnw network. There are three lines, one 2W-transformer and one fixed shunt at the bus. The bus voltage is the reference angle (0 degrees).
