Low-Resolution Fault Localization Using Phasor Measurement Units with Community Detection [PDF]
, 2018 A significant portion of the literature on fault localization assumes (more or less explicitly) that there are sufficient reliable measurements to guarantee that the system is observable. While several heuristics exist to break the observability barrier,
