A New Approach of Exploiting Self-Adjoint Matrix Polynomials of Large Random Matrices for Anomaly Detection and Fault Location
Zenan Ling, Robert C. Qiu, Xing He +1
Synchronized measurements of a large power grid enable an unprecedented opportunity to study the spatialtemporal correlations. Statistical analytics for those massive datasets star…
Early Anomaly Detection and Location in Distribution Network: A Data-Driven Approach
Xin Shi, Robert Qiu, Xing He +3
The measurement data collected from the supervisory control and data acquisition (SCADA) system installed in distribution network can reflect the operational state of the network e…
A Data-driven Approach to Multi-event Analytics in Large-scale Power Systems Using Factor Model
Fan Yang, Xing He, Robert Caiming Qiu +1
Multi-event detection and recognition in real time is of challenge for a modern grid as its feature is usually non-identifiable. Based on factor model, this paper porposes a data-d…
Invisible Units Detection and Estimation Based on Random Matrix Theory
Xing He, Lei Chu, Robert C. Qiu +3
Invisible units mainly refer to small-scale units that are not monitored by, and thus are not visible to utilities. Integration of these invisible units into power systems does sig…
Spatio-Temporal Big Data Analysis for Smart Grids Based on Random Matrix Theory: A Comprehensive Study
Robert Qiu, Lei Chu, Xing He +2
A cornerstone of the smart grid is the advanced monitorability on its assets and operations. Increasingly pervasive installation of the phasor measurement units (PMUs) allows the s…
A Novel Approach for Big Data Analytics in Future Grids Based on Free Probability
Zenan Ling, Robert C. Qiu, Xing He +1
Based on the random matrix model, we can build statistical models using massive datasets across the power grid, and employ hypothesis testing for anomaly detection. First, the aim…
Massive Streaming PMU Data Modeling and Analytics in Smart Grid State Evaluation Based on Multiple High-Dimensional Covariance Tests
Lei Chu, Robert Qiu, Xing He +2
The analogous deployment of phase measurement units (PMUs), the increase of data quantum and the deregulation of energy market, all call for the robust state evaluation in large sc…
