Abstract
This paper proposes an estimation method of power system impedance based on power variations caused by a
distributed power generation system (DPGS) at the point of common coupling (PCC). The proposed algorithm is
computationally simple and uses the voltage variations at the point of common coupling (PCC) caused by the
variations of the power delivered to utility network to derive the value of grid impedance. Accurate estimation of
both resistive and inductive part of the impedance is obtained, as the results presented show.
