Thevenin's equivalent of photovoltaic source models for MPPT and power grid studies
2011 IEEE Power and Energy Society General Meeting, 2011The model of a photovoltaic (PV) source is needed for Maximum Power Point Tracking (MPPT) and power grid studies. The single diode model can fairly emulate PV's characteristic. The only nonlinear element in this model is the single diode. This paper proposes Thevenin's equivalent model for a PV source by piecewise linearization of the diode ...

Comparison of Simple Battery Model and Thevenin Battery Model for SOC Estimation Based on OCV Method
2019 International Conference on Information and Communications Technology (ICOIACT), 2019State of Charge (SOC) is a component of Battery Management System (BMS) which gives information on the remaining capacity of a battery. For monitoring purpose, SOC estimation is represented as ratio of the remaining capacity to the nominal capacity of a battery.

THEVENIN EQUIVALENT CIRCUITS FOR MODELING COMMON-MODE BEHAVIOR IN POWER ELECTRONIC SYSTEMS
2021The high-frequency switching of transistors in power electronic (PE) converters is known to cause unintended common-mode (CM) current that flows through parasitically-coupled ground paths. One way to model these currents is to utilize time-domain simulations that capture switching dynamics and the corresponding parasitic response.

Effect of anode conductivity degradation on the Thevenin Circuit Model of lithium ion batteries
IECON 2016 - 42nd Annual Conference of the IEEE Industrial Electronics Society, 2016This paper proposes a high resolution anode degradation model of the lithium ion battery based on its physics of operation in 3D and in layers. This model is developed in a multiphysics software called COMSOL and in Matlab. This paper describes the procedure followed to develop the model in 3D and the features of this model.

Battery parameters identification is crucial for accurate prediction of battery life in electric vehicles. In order to optimize battery parameter identification, an improved PSO (particle swarm optimization) algorithm was proposed based on the use of Thevenin battery model to abstract the problem into an optimization problem.

Osculating Thevenin model for predicting delay and slew of capacitively characterized cells
Proceedings 2002 Design Automation Conference (IEEE Cat. No.02CH37324), 2002To extrapolate from one point to another using a line, one had better get the slope right. In this paper we apply a similar concept to the important problem in Static Timing Analysis (STA) of predicting cell timing for RC loads using capacitive characterization data.

2010 International Conference on Optics, Photonics and Energy Engineering (OPEE), 2010
Based on artificial neural networks and Thenvenin model, this paper uses an improved model predicting state of charge. We combine artificial neural networks model with Thevenin model, and predict state of charge in real time at the same time. When the difference between the predictive value of artificial neural networks model and the predictive value ...

Modeling of Islanded Microgrids Using Static and Dynamic Equivalent Thevenin Circuits
2018In this paper, a new modeling method based on the equivalent Thevenin circuit is proposed for inverter-interfaced microgrids. The proposed method approximates the entire network connected to each inverter with an equivalent Thevenin circuit. The equivalent circuit is studied in two forms: static impedance and dynamic second-order RL branch.

A Parameter Extraction Method for the Thevenin Equivalent Circuit Model of Li-ion Batteries
2019 IEEE Industry Applications Society Annual Meeting, 2019This paper presents a novel parameter extraction method for the Thevenin equivalent circuit model of Lithium-ion batteries. The proposed approach represents each of the RC parallel branches of the Thevenin equivalent circuit model of a Lithium-ion battery as a first order linear time-invariant (LTI) system.
