Most recently, the stability issues for a weak power grid with high penetration of PV generators raise great interests. Under this type of operational condition, the impedance model of a PV inverter was widely used. Cespedes and Sun (2014) modeled the inverter by a positive-sequence and a negative-sequence impedance directly in the phase domain.
