General treatment to calculate the Thevenin equivalent circuit
American Journal of Physics, 1978The method to calculate the Thevenin (or Norton) equivalent circuit of networks containing controlled current and/or voltage sources is identical to the method used with purely passive circuits if the fundamental concept of equivalence of networks is properly understood.

Thevenin equivalent parameter tracking for on-line voltage stability assessment
2015 IEEE Innovative Smart Grid Technologies - Asia (ISGT ASIA), 2015This paper demonstrated a method for online voltage stability assessment of a load bus using bus phasor measurements. The power system is represented by Thevenin equivalent model, which parameters are estimated by applying new methods based on discrete Kalman filter (DKF) and unscented Kalman filter (UKF). Voltage stability index is calculated based on

One-step Evaluation of the Thevenin Equivalent Circuit
IETE Journal of Education, 2003In the usual procedure to determine the Thevenin equivalent of a network N, two separate analyses are needed, one for finding the open-circuit voltage and the other for the evaluation of the Thevenin impedance. This note outlines a method to accomplish this task after the analysis of a single network.

A comparative study of measurement-based Thevenin equivalents identification methods
2014 North American Power Symposium (NAPS), 2014With the development of phasor measurement units (PMU), real-time voltage stability monitoring techniques using phasor measurements have been widely discussed in the past decade. For various measurement-based techniques, the fundamental idea behind them is to identify the Thevenin equivalents (TE) of the outer system seen from the nodes/areas of ...

Thevenin equivalent circuit parameter estimation for the PCC upstream system
2015 5th International Conference on Electric Utility Deregulation and Restructuring and Power Technologies (DRPT), 2015The Thevenin equivalent circuit parameters for the upstream system seen at a load bus plays an important role in the power system operation and planning. In order to accurately estimate the Thevenin equivalent parameters for the upstream supply system, an estimation method not requiring synchronized measurement is used in this paper.
