Influence of Measurement Uncertainties on the Quality of Grid Topology Identification in Three-Phase Systems

Due to the increase in decentralized generation plants and the emergence of new customer types, distribution grid operators will face an increased need to perform grid status analyses based on measurement data collected by smart metering systems. The necessary grid topology, however, is not available to distribution grid operators in sufficient quality in many cases. This paper presents an extension of an existing topology identification method based on measurement data of three-phase systems. Within the scope of sensitivity analyses, the influence of measurement uncertainties is investigated and compared with the current state of deployed measurement technology in Europe.
