摘要
•In this paper a frequency domain formulation for fault location in distribution networks with Distributed Energy Resources is presented.•The fault location method is formulated as a minimization problem. A Fibonacci-based search method is proposed to improve the estimation process.•Inherent characteristics as unbalanced operation, different load types and non-transposed lines are considered during method́s equation development.•Different Distributed Energy Resources are considered through a ladder-based approach.•The proposed method showed to be efficient and robust, using only locally available voltage and current phasors and synchronized current phasors in each DER.
