A Spectral Representation of Power Systems with Applications to Adaptive Grid Partitioning and Cascading Failure Localization
Alessandro Zocca, Chen Liang, Linqi Guo +2
Transmission line failures in power systems propagate and cascade non-locally. This well-known yet counter-intuitive feature makes it even more challenging to optimally and reliabl…
Line Failure Localization of Power Networks Part II: Cut Set Outages
Linqi Guo, Chen Liang, Alessandro Zocca +2
Transmission line failure in power systems prop-agate non-locally, making the control of the resulting outages extremely difficult. In Part II of this paper, we continue the study…
Adaptive Network Response to Line Failures in Power Systems
Chen Liang, Linqi Guo, Alessandro Zocca +2
Transmission line failures in power systems propagate and cascade non-locally. In this work, we propose an adaptive control strategy that offers strong guarantees in both the mitig…
Line Failure Localization of Power Networks Part I: Non-cut Outages
Linqi Guo, Chen Liang, Alessandro Zocca +2
Transmission line failures in power systems propagate non-locally, making the control of the resulting outages extremely difficult. In this work, we establish a mathematical theory…
An Integrated Approach for Failure Mitigation & Localization in Power Systems
Chen Liang, Linqi Guo, Alessandro Zocca +3
The transmission grid is often comprised of several control areas that are connected by multiple tie lines in a mesh structure for reliability. It is also well-known that line fail…
Less is More: Real-time Failure Localization in Power Systems
Linqi Guo, Chen Liang, Alessandro Zocca +2
Cascading failures in power systems exhibit non-local propagation patterns which make the analysis and mitigation of failures difficult. In this work, we propose a distributed cont…
Failure Localization in Power Systems via Tree Partitions
Linqi Guo, Chen Liang, Alessandro Zocca +2
Cascading failures in power systems propagate non-locally, making the control and mitigation of outages extremely hard. In this work, we use the emerging concept of the tree partit…
Graph Laplacian Spectrum and Primary Frequency Regulation
Linqi Guo, Changhong Zhao, Steven H. Low
We present a framework based on spectral graph theory that captures the interplay among network topology, system inertia, and generator and load damping in determining the overall…
