On Thevenin's and Norton's Equivalent Circuits
IEEE Transactions on Education, 1982This paper provides a good look at the concept of equivalence in general and at Thevenin's and Norton's theorems in particular. The ain is to investigate simple, general, and comprehensive ways to present and prove these theorems. It is shown that linearity and the absence of external coupling should not be conditions for Thevenin's and Norton's ...

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.

On-line estimation of thevenin equivalent with varying system states
2008 IEEE Power and Energy Society General Meeting - Conversion and Delivery of Electrical Energy in the 21st Century, 2008For power system, Thevenin equivalent at a node can represent the aggregation of systempsilas operation conditions, e.g. generator terminal voltages, load powers, and line impedances, seen from a bus. estimation of Thevenin equivalent can be challenging given that active controls in power systems vary the systempsilas states with time.

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.

Analysis of thevenin equivalent network of a distribution system for solar integration studies
2012 3rd IEEE PES Innovative Smart Grid Technologies Europe (ISGT Europe), 2012The high target of EU renewable standard, increasing technology investment and the cost reduction are nowadays the main driving factors for the renewable generation penetration. As a reliable energy resource, solar energy from photovoltaics (PVs) is seen as one of the important renewable generations and expected to play a significant role in the future

Thevenin equivalent circuit for the study of high photovoltaic penetration in distribution grids
IEEE PES ISGT Europe 2013, 2013The electricity grid is unidirectional operating in a passive way and consequently it is not yet ready to accept high penetration of renewable energy sources (RES). Further research is required to assess the impact of distributed Photovoltaic (PV) generation on power quality and establish the necessary measures for the restructuring of the electricity ...

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.

Fault locating estimation using thevenin equivalent in power systems
2010 Conference Proceedings IPEC, 2010This paper develops a method to acquire the relationships between the real fault distance and the varying Thevenin equivalent impedance. Multiple measurements have been taken from simulations of the Taiwan power system and their Thevenin equivalent have been calculated.

Limitations of the Thevenin and Norton equivalent circuits for a receiving antenna
IEEE Antennas and Propagation Magazine, 2003The investigation carried out in this paper was stimulated by a recent paper published by Love (2002), in which the appropriateness of the use of the Thevenin and Norton equivalent circuits for a receiving antenna was questioned. A review of the available literature led to the conclusion that the limitations inherent in the Thevenin and Norton ...
