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,

Measurement accuracy verification of phasor measurement unit with dynamic phasor estimation
Archives of Electrical Engineering, 2018 Power systems that are highly loaded, especially by a stochastic supply of renewables and the presence of storages, require dynamic measurements for their optimal control. Phasor measurement units (PMUs) can be used to capture electrical parameters of a power system.
