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.

Current estimation using Thevenin battery model
Proceedings of the Joint International Conference on Electric Vehicular Technology and Industrial, Mechanical, Electrical and Chemical Engineering (ICEVT & IMECE), 2015Current sensor is an important part of Battery Management System (BMS). Current information of a battery is very important to estimate the value of State of Charge (SOC) as a component of fault detection. Fault detection is very important to implement in BMS because of its function to protect battery from damage caused by over discharge and overcharge.

Modeling of voltage source converters in microgrids using equivalent thevenin circuit
2018 9th Annual Power Electronics, Drives Systems and Technologies Conference (PEDSTC), 2018In 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

Calculating the Effective Capacitance for Interconnect Loads Based on Thevenin Model
2006 International Conference on Communications, Circuits and Systems, 2006Interconnect wires give large influences on circuit delay in very deep submicron designs. Thevenin model and effective capacitance Ceff concept are usually used to calculate the delay of gate with interconnect loads. In the researches before, the condition that the charges transferred to Ceff and RC - ?are not equal was not considered.
