Influence of Phasor Measurement Unit Accuracy on State Estimation in Power System

Popis výsledku v původním jazyce

State estimation in power system is an iterative solution problem in nature due to the nonlinear relation between measurements and system state variables. Consequently, estimated results will be approximated. The advancement in phasor measurement technology brings new opportunities to improve the state estimation performance by eliminating the nonlinearity issues. In this paper, a phasor measurement-based linear state estimator for IEEE 14 bus system is presented and it has been examined for different possible measurement errors according to Monte Carlo theory. The test was performed as per the IEEE Std. C37.118.1 -2011. The superiority of the linear state estimator over the conventional state estimator in respects of accuracy and robustness will be highlighted. The influence of phasor voltage measurement errors and current measurement errors on the state estimation result will be comprehensively investigated and discussed in this work.
