Wind-Storage Combined Virtual Inertial Control Based on Quantization and Regulation Decoupling of Active Power Increments

Energies, 2022
With the increasing proportion of wind turbines in power grids, they are required to have capabilities of active and efficient virtual inertial response to maintain grid frequency stability. However, the virtual inertial control methods currently used in

Modulation of homogeneous turbulence seeded with finite size bubbles or particles [PDF]

, 2010
The dynamics of homogeneous, isotropic turbulence seeded with finite sized particles or bubbles is investigated in a series of numerical simulations, using the force-coupling method for the particle phase and low wavenumber forcing of the flow to sustain

Observations of the upper ocean response to storm forcing in the South Atlantic Roaring Forties [PDF]

Annales Geophysicae, 1995
In the austral summer of 1992–1993 the passage of a storm system drove a strong upper ocean response at 45°S in the mid-South Atlantic. Good in situ observations were obtained.

Local equilibrium and the second law of thermodynamics for irreversible systems with thermodynamic inertia [PDF]

, 2015
Validity of local equilibrium has been questioned for non-equilibrium systems which are characterized by delayed response. In particular, for systems with non-zero thermodynamic inertia, the assumption of local equilibrium leads to negative values of the

An inertial droop control based on comparisons between virtual synchronous generator and droop control in inverter-based distributed generators

Energy Reports, 2020
The adoption of the droop control provides a feasible scheme for the distributed generation connected to the utility grid. Nevertheless, it does not contribute to the inertia and damping factor necessary for power systems.

Integral curses of the disc drama model with fundamental dynamic characteristics tt-ds [PDF]

Journal of Research and Innovation for Sustainable Society, 2019
The paper deals with the dynamic response of mechanisms with standardized inertial and mechanical characteristics. Moment or inertial mass is periodically variable with displacement, and torque or mechanical force are periodically variable with ...

The exponential law: Monopole detectors, Bogoliubov transformations, and the thermal nature of the Euclidean vacuum in RP^3 de Sitter spacetime

, 1998
We consider scalar field theory on the RP^3 de Sitter spacetime (RP3dS), which is locally isometric to de Sitter space (dS) but has spatial topology RP^3.

Inertial waves in rapidly rotating flows: a dynamical systems perspective [PDF]

, 2016
An overview of recent developments in a wide variety of enclosed rapidly rotating flows is presented. Highlighted is the interplay between inertial waves, which have been predicted from linear inviscid considerations, and the viscous boundary layer ...

Response of a swirl flame to inertial waves [PDF]

International Journal of Spray and Combustion Dynamics, 2017
Acoustic waves passing through a swirler generate inertial waves in rotating flow. In the present study, the response of a premixed flame to an inertial wave is scrutinized, with emphasis on the fundamental fluid-dynamic and flame-kinematic interaction mechanism.
