Environmental drivers have seen an exponential uptake of residential photo-voltaic (PV) systems in many parts of the world. PV intermittency and unpredictability have presented new challenges to the electricity generation, transmission and distribution sectors. From a power quality perspective, these PV systems cause additional flicker, unbalance and steady-state voltage fluctuations within distribution...
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...
