This paper proposes an improved algorithm for tracking the Thévenin equivalent parameters with local phasor measurements for voltage stability analysis. Estimation errors between the Thévenin equivalent voltage and impedance are mathematically formulated, and then used to correct the equivalent parameters with two subsequent measurements. This algorithm does not introduce any parameters drift problems and does not need a large data window to converge. A 2-bus test system, the IEEE 14-buses system and an actual 500kV grid system from China are used to test the proposed algorithm. Test results indicate that this algorithm is accurate, robust and fast for real time voltage stability monitoring and control.
