A Dynamic Model of Impedance for Online Thevenin’s Equivalent Estimation
IEEE Transactions on Circuits and Systems II: Express Briefs, 2022A time domain dynamic model of impedance has been developed in this work for online estimation of Thevenin’s equivalent impedance of a network seen from a bus. Although the time domain impedance (ratio of instantaneous AC voltage and current) is undefined in a period, a zone of definition and workability has been defined.

Voltage stability assessment using equivalent Thevenin
2015 IEEE Thirty Fifth Central American and Panama Convention (CONCAPAN XXXV), 2015The voltage stability in the power systems operation has taken importance due to the restrictions in the network when there is a growing demand. This has motivated hundreds of researchers to develop methods to detect the voltage instability's proximity, which reduces computational time and helps to take accurate decisions, guaranteeing a reliable and ...

Improvement of Thevenin Equivalent Parameters and Computations
Advanced Materials Research, 2012In this paper, the conventional method to acquire Thevenin equivalent parameters is described. The method is based on features of power systems and utilizes the base-case system information. Considering the impact of loads on Thevenin equivalent potential and impedance, this paper makes improvements and brings it closer to the actual situation.

Circuit diagnosis and Thevenin equivalents
Proceedings of the IEEE, 1982Roytman and Swamy have used the properties of orthonormal excitations to establish one method of circuit diagnosis. In this letter the method is extended to determine the driving-point or Thevenin equivalent impedance for each node pair.
