Optimum Placement of Phasor Measurement Units in Power Systems [PDF]
IEEE Transactions on Instrumentation and Measurement, 2019 In this paper, we proposed to evaluate the optimal phasor measurement unit (PMU) placement based on the sum of variance (SV) of the robust estimators. Variance is traditionally used as a measure of the quality of estimates. In this paper, after satisfying the requirements of the minimum number of PMUs, maximum measurement redundancy, and observability,

Phasor Measurement Unit Test Under Interference Conditions [PDF]
IEEE Transactions on Power Delivery, 2018 This paper investigates the performance of phasor measurement units (PMUs) under interference conditions, which can appear in a power system and are not tested by the C37.118.1 standard. Three PMUs from different vendors configured for the M-class requirements were used to test three possible interference condition scenarios.
