A Framework for Phasor Measurement Placement in Hybrid State Estimation via Gauss-Newton
, 2013 In this paper, we study the placement of Phasor Measurement Units (PMU) for enhancing hybrid state estimation via the traditional Gauss-Newton method, which uses measurements from both PMU devices and Supervisory Control and Data Acquisition (SCADA ...

Technique for pre-compliance testing of phasor measurement units [PDF]
International Journal of Electrical Power & Energy Systems, 2018 Abstract This paper introduces a technique for ‘pre-compliance’ testing of Phasor Measurement Units (PMUs) against the dynamic requirements of the IEEE C37.118.1-2014 standard, which include dynamic and steady-state test scenarios. The tests described are a necessary, but not complete, requirement for passing the IEEE standard and quickly highlight ...
