Small-Signal Distributed Frequency Modeling and Analysis for Grid-Forming Inverter-Based Power Systems

open access: yesFrontiers in Energy Research, 2022
More and more renewable energy sources are integrated into power grids, leading to a power electronic-based low-inertia power system. The grid-forming (GFM) inverter is an effective method for improving the inertia of the system.

Virtual Inertia Control and Small-Signal Stability Analysis of Electric Vehicle [PDF]

open access: yesInternational Journal of Industrial Electronics, Control and Optimization, 2023
In electric vehicles (EVs), the small size of the dc link capacitor results in significant voltage deviations when there are changes in load or uncertain fluctuations from the power resources. This causes a decline in voltage quality.

Generalized small-signal modelling of dual active bridge DC/DC converter [PDF]

open access: yes, 2018
this paper presents a novel generalised approach of the small-signal modelling of dual active bridge (DAB) DC/DC converter. The adopted analysis is based on a per-unit fundamental frequency representation of the DAB. The outcome of the proposed modelling

Small-Signal Model of STATCOM and Its Model Validation [PDF]

open access: yes2018 IEEE Power & Energy Society General Meeting (PESGM), 2018
This paper proposes a small-signal model of STATCOM based on theoretical derivation. This theoretical model is obtained by linearization of the dc-link control loop, Phase-Locked Loop (PLL), ac voltage control loop under the weak grid condition. In order to validate the correctness of this small-signal model, an identified model in the form of transfer

Compact conversion and cyclostationary noise modelling of pn junction diodes in low-injection - Part I: Model derivation [PDF]

open access: yes, 2004
Starting from the well known low-injection approximation, a closed form, analytical compact model is derived for the small-signal (SS) and forced quasi-periodic operation of junction diodes. The model determines the small-signal and conversion admittance

Research on a Modeling and Control Strategy for Interleaved Boost Converters with Coupled Inductors

open access: yesEnergies, 2023
Interleaved DC–DC converters have significant advantages in improving the capability of power converters, and coupling the filtering inductor of the converter could further increase the power density. However, existing modeling and controller designs are

A lava attack on the recovery of sums of dense and sparse signals [PDF]

open access: yes, 2015
Common high-dimensional methods for prediction rely on having either a sparse signal model, a model in which most parameters are zero and there are a small number of non-zero parameters that are large in magnitude, or a dense signal model, a model with ...

Synchronous Generator Imitation Control and Dynamic Power Sharing for Distributed Power Generation Systems

open access: yesFrontiers in Energy Research, 2022
In this paper, a control method called synchronous generator imitation control (SGIC) as well as a dynamic power sharing for distributed power generation systems (DPGSs) are presented. In order to imitate the behavior of a synchronous generator (SG), the
