Dimensionality Increment of PMU Data for Anomaly Detection in Low Observability Power Systems
Xin Shi, Robert Qiu
Anomaly detection is an important task in power systems. To make better use of the phasor measurement unit (PMU) data collected from a low observability power system for anomaly de…
Asymptotics of empirical eigenvalues for large separable covariance matrices
Tiebin Mi, Robert Caiming Qiu
We investigate the asymptotics of eigenvalues of sample covariance matrices associated with a class of non-independent Gaussian processes (separable and temporally stationary) unde…
Preliminary Exploration on Digital Twin for Power Systems: Challenges, Framework, and Applications
Xing He, Qian Ai, Robert C. Qiu +1
Digital twin (DT) is one of the most promising enabling technologies for realizing smart grids. Characterized by seamless and active---data-driven, real-time, and closed-loop---int…
Early Anomaly Detection in Power Systems Based on Random Matrix Theory
Xin Shi, Robert Qiu
It is important for detecting the anomaly in power systems before it expands and causes serious faults such as power failures or system blackout. With the deployments of phasor mea…
Robust Precoding Design for Coarsely Quantized MU-MIMO Under Channel Uncertainties
Lei Chu, Fei Wen, Robert Caiming Qiu
Recently, multi-user multiple input multiple output (MU-MIMO) systems with low-resolution digital-to-analog converters (DACs) has received considerable attention, owing to the capa…
LEMO: Learn to Equalize for MIMO-OFDM Systems with Low-Resolution ADCs
Lei Chu, Ling Pei, Husheng Li +1
This paper develops a new deep neural network optimized equalization framework for massive multiple input multiple output orthogonal frequency division multiplexing (MIMOOFDM) syst…
