For being able to consider frequency dependent network impedance you must use the Voltage Source element instead of the External Network. The short circuit impedance must here be defined by R and X in Ohms.
On the Harmonics-page, frequency characteristics for R and L could be defined.
For more information about the Voltage Source, refer to the technical reference of the element AC Voltage Source (ElmVac).

First of all, it must be stressed that such analysis considers a steady state of the linear network. Otherwise, a time-frequency approach must be applied. In the case of power systems with nonlinear loads the harmonic analysis is usually performed under some assumptions:
for each harmonic any nonlinear load can be represented by a current source,
the impedance matrix describing the system can be determined separately for each frequency.
