The effect of phasor measurement units on the accuracy of the network estimated variables
HA Sangrody, MT Ameli… - … on Developments in …, 2009 - ieeexplore.ieee.org
The most commonly used weighted least square state estimator in power industry is
nonlinear and formulated by using conventional measurements such as line flow and
injection measurements. PMUs (Phasor Measurement Units) are gradually adding them to
improve the state estimation process. In this paper the way of corporation the PMU data to
the conventional measurements and a linear formulation of the state estimation using only
PMU measured data are investigated. Six cases are tested while gradually increasing the …
