Abstract

This paper proposes a fault location identification method for power distribution systems with inverter-interfaced distributed generations (IIDGs). The proposed method is not restricted to any specific types of data and is able to fully utilize all available types of data in power distribution systems for enhancing the accuracy of results. The measurement set may include synchronized voltage and current measurements collected by Micro-phasor measurement units (Micro-PMUs) and/or unsynchronized measurements collected by legacy measuring devices, active and reactive power measurements, pseudo measurements of load values, and virtual measurements based on Kirchhoff’s laws. The proposed method explicitly considers uncertainties in the measurement set and is applicable for different load types. Simulations results on IEEE 34-bus feeder demonstrate the accuracy of the proposed method.
