Abstract

This letter presents a robust voltage instability predictor using local noisy PMU measurements. A robust recursive least squares estimation is proposed to mitigate the impacts of gross PMU measurement errors on estimating the bus impedance and the Thevenin equivalent impedance used for voltage stability analysis. Numerical results on the IEEE 39-bus system validate the effectiveness and robustness of the proposed method.
