Parameswaran, Saththiyan, Dey, Maitreyee and Patel, Preeti (2025) Micro-PMU data-driven anomalous voltage event detection for the power distribution system. In: 12th International Conference on Frontiers of Intelligent Computing: Theory and Applications (FICTA-2024), 6-7 June 2024, London Metropolitan University, London (UK) / Online.
As Distributed Energy Resources become more prevalent in the power grid, the challenges facing grid operators have intensified. The integration of micro-synchrophasors (micro-PMUs) into the grid infrastructure has provided access to high-resolution data, yet analyzing such vast amounts of information presents its own set of obstacles. This study examines thirty days of micro-PMU data from April 2023, employing statistical analysis and unsupervised learning techniques to identify various voltage events over time. Real-world data from grid-connected solar farms in Norfolk, England, is utilized to detect and analyze these voltage events, as well as to explore their distinct patterns.
