The interconnection stability of a grid-connected voltage-source converter (VSC) can be assessed by the passivity properties of the VSC input admittance. If critical grid resonances fall within regions where the input admittance acts passively, i.e., has nonnegative real part, then their destabilization is generally prevented.

A shunt active filter operated as a harmonic conductance is able to suppress a harmonic resonance in the distribution power system. However, due to the inherent phase-lagging in digital signal processing, the active filter really behaves as a harmonic admittance instead of conductance.
