Interface Networks for Failure Localization in Power Systems

Chen Liang, Alessandro Zocca, Steven H. Low +1

Transmission power systems usually consist of interconnected sub-grids that are operated relatively independently. When a failure happens, it is desirable to localize its impact wi…

Refining bridge-block decompositions through two-stage and recursive tree partitioning

Leon Lan, Alessandro Zocca

In transmission networks power flows and network topology are deeply intertwined due to power flow physics. Recent literature shows that specific network substructures named bridge…

Hopping between distant basins

Maldon Goodridge, John Moriarty, Jure Vogrinc +1

We present the Basin Hopping with Skipping (BH-S) algorithm for stochastic optimisation, which replaces the perturbation step of basin hopping (BH) with a so-called skipping propos…

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…
