Multi-SIN-Based Real-Time Impedance Estimation for Self-Commissioning Controller and Active Damping in an LCL-Grid-Tied VSI

IEEE Open Journal of Industry Applications
This article introduces a novel method for self-commissioning controllers and active damping in LCL grid-tied three-phase voltage source inverters. The proposed impedance estimation method is designed with the goal of minimizing invasiveness on the grid ...

Wide frequency range active damping of LCL-filtered grid-connected converters

The Journal of Engineering, 2019
It can be challenging to guarantee the stability of grids with many converters with LCL filters connected due to the presence of multiple resonances within the system. This paper presents an active damping technique to mitigate multiple resonance effects

Semi-Active Cable Damping to Compensate for Damping Losses Due to Reduced Cable Motion Close to Cable Anchor

Applied Sciences, 2022
The relative motion of transverse cable dampers is smaller than predicted by the taut string model because of the effects of bending stiffness and fixed support conditions.

Electromagnetic waves in an axion-active relativistic plasma non-minimally coupled to gravity

, 2013
We consider cosmological applications of a new self-consistent system of equations, accounting for a nonminimal coupling of the gravitational, electromagnetic and pseudoscalar (axion) fields in a relativistic plasma.

Understanding and Optimizing Li Substitution in P2‐Type Sodium Layered Oxides for Sodium‐Ion Batteries

Advanced Functional Materials, EarlyView.
This work explores Li‐substituted P2 layered oxides for Na‐ion batteries by crystallographic and electrochemical studies. The effect of lithium on superstructure orderings, on phase transitions during synthesis and electrochemical cycling and on the interplay of O‐ versus TM‐redox is revealed via various advanced techniques, including semi‐simultaneous

Escape rate of an active Brownian particle over a potential barrier

, 2012
We study the dynamics of an active Brownian particle with a nonlinear friction function located in a spatial cubic potential. For strong but finite damping, the escape rate of the particle over the spatial potential barrier shows a nonmonotonic ...

Modulating Two‐Photon Absorption in a Pyrene‐Based MOF Series: An In‐Depth Investigation of Structure–Property Relationships

Advanced Functional Materials, EarlyView.
This study investigates H4TBAPy‐based metal–organic frameworks (MOFs) ‐ NU‐1000, NU‐901, SrTBAPy, and BaTBAPy ‐ for multiphoton absorption (MPA) performance. It observes topology‐dependent variations in the 2PA cross‐section, with BaTBAPy exhibiting the highest activity.

A weighted damping strategy for improving the adaptability of converter to weak grid

Diance yu yibiao
Active damping can significantly improve the adaptability of converter to weak grid, however, when the PCC (point of common coupling) voltage harmonics are used for active damping control, the suppression ability of the system on the background harmonic ...

Collective Light Emission of a Finite Size Atomic Chain

, 2012
Radiative properties of collective electronic states in a one dimensional atomic chain are investigated. Radiative corrections are included with emphasize put on the effect of the chain size through the dependence on both the number of atoms and the ...
