Adaptive undervoltage load shedding relay design using Thevenin equivalent estimation

2008 IEEE Power and Energy Society General Meeting - Conversion and Delivery of Electrical Energy in the 21st Century, 2008
Power transmission systems of today are operating closer to their limit. In the event of a developing blackout, the disconnection of loads under controlled conditions can maintain system's stability. Undervoltage load shedding (UVLS) is an economical solution to the voltage stability problem, and provides protection for unusual disturbances outside the

Determination of the Frequency Dependent Thévenin Equivalent of Inverters Using Differential Impedance Spectroscopy

International Symposium on Power Electronics for Distributed Generation Systems, 2020
This paper introduces a measurement technique that allows grid-connected inverters to be interpreted as frequency-dependent Thévenin equivalents. By means of this so-called differential impedance spectroscopy it is possible to determine the spectrum of ...

Analysis of 2D lumped circuit by equivalent Thevenin source method

14th International Conference on Microwaves, Radar and Wireless Communications. MIKON - 2002. Conference Proceedings (IEEE Cat.No.02EX562), 2003
This paper presents an equivalent Thevenin source (ETS) method for analysis of two-dimensional (2D) circuits. The analysis is based on the decomposition of a 2D RLGC circuit into cascade-connected ladder subnetworks with 2L ports. For each ladder subnetwork, corresponding transmission matrices are counted and all previous subnetworks are than ...

Modeling of voltage source converters in microgrids using equivalent thevenin circuit

2018 9th Annual Power Electronics, Drives Systems and Technologies Conference (PEDSTC), 2018
In this paper, a new modelling approach based on the equivalent Thevenin circuit is proposed for voltage source converters in islanded microgrids. The proposed method approximate the entire network connected to the voltage source converter with an equivalent Thevenin circuit. The equivalent circuit is first considered with a non-dynamic impedance. This

A Hybrid Fault Cluster and Thévenin Equivalent Based Framework for Rotor Angle Stability Prediction

IEEE Transactions on Power Systems, 2018
This paper addresses a novel approach for rotor angle stability prediction in power systems. In the proposed framework, a fault cluster (FC) concept is introduced to divide an electrical network into several disparate zones.

Multi-port Thévenin’s Theorem: A New Matrix Formulation and Efficient Calculation Method of Equivalent Circuit Constants

International Conference on Embedded and Multimedia Computing
A new matrix formulation for the multi-port Théenin’s theorem is proposed, which allows each port to be represented by a single equivalent source, while specifying whether it is a voltage or current source.
