A “big data” challenge — Turning smart meter voltage quality data into actionable information

This paper provides analysis of over and under voltage events captured by smart meters. Using data analysis techniques, the relationship of voltage events is analyzed with respect to ambient temperature, times of the day, days of the week, duration, magnitude and embedded generation status. Clusters of voltage violation sites are grouped to upstream supply distribution substations and zone substations. The analysis forms the basis of proactive voltage improvement that can be undertaken by the supply utility.
