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…
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…
