As ffl wrote in his comment you can plot the admittance in VAR(L+2).
Reactive power Q can be plotted in two ways:
- Multiply the admittance with the
voltage in square when plotting.
- Split the bus and move the switched
shunt to the new bus. Add MW & Mvar
channels for the zero impedance line
inserted between the new bus and the
original bus.
I prefer alternative 2.
