Overview of Topology Identification for Low-voltage Distribution Network

Topology identification of low-voltage distribution network is beneficial to ensure the safe and reliable operation of distribution network and the asset management of utilities, which is the basis of distribution network system analysis. In this paper, the existing topology identification methods are divided into two categories. The first type is based on measurement data, including the correlation analysis, cluster analysis, linear programming and neural network. The second type is based on communication signal transmission and uses power line carrier communication for topology recognition. Finally, the existing methods are compared and concluded and the outlook of future work is given.
