Impact of steady-state grid-frequency deviations on the performance of grid-forming converter control strategies

2020 22nd European Conference on Power Electronics and Applications (EPE'20 ECCE Europe), 2020
The aim of this paper is to investigate the impact of steady-state deviations in the grid-frequency on the performance of grid-forming converter control strategies. In particular, the virtual synchronous machine (VSM) control structure has been the focus of study in this paper.

The properties of the kernels of the Volterra series describing flow deviations from a steady state in an open channel

Journal of Hydrology, 1981
Abstract The deviation of the flow from a steady state in an open channel is described by a nonlinear state equation. This model is used to derive analytically the kernels of the Volterra series. The properties and the structure of the two first kernels are examined.

Indications of linearity deviations of steady-state concentration profiles in hydrogen permeation membranes

International Journal of Hydrogen Energy, 1995
Abstract In the course of studies of permeation of electrolytically generated hydrogen through membranes of palladium and the palladium alloy Pd77Ag23, further observations have been made of steady-state permeation rate accelerations on interruption of electrolysis.

Effects of gravity on the steady state of a reaction in a liquid-state microreactor—deviations from Poiseuille flow

Physical Chemistry Chemical Physics, 2003
We have simulated the steady state of a stoichiometric neutralisation reaction in a capillary flow reactor. The reactive flow occurs in an upright capillary tube with coaxial inlets in its base, an open top and with adiabatic sidewalls. A dilute solution of 0.100 M alkali or acid is injected vertically upwards through the central inlet.

Analysis of Deviations from Steady State Performance During Transient Operation of a Light Duty Diesel Engine

SAE International Journal of Engines, 2012
<div class="section abstract"><div class="htmlview paragraph">Deviations between transient and steady state operation of a modern light duty diesel engine were identified by comparing rapid load transitions to steady state tests at the same speeds and fueling rates.

Deviations from minimum entropy production at steady states of reacting chemical systems arbitrarily close to equilibrium

Physica A: Statistical Mechanics and its Applications, 1988
Abstract Our analysis of reacting systems displaced from equilibrium by a matter flux across the boundaries has shown that the state of minimum entropy production differs from the steady state, even in the near equilibrium regime. When the displacement δ from equilibrium is small, the derivative of the dissipation at the steady state and the ...

Chemical potentials in driven steady-state systems in contact : a large deviation approach

Potentiels chimiques dans des systèmes stationnaires hors d'équilibre en contact : une approche par les grandes déviations Cette thèse porte sur la physique statistique des systèmes hors d’équilibre maintenus dans un état stationnaire. Plus spécifiquement, ce travail s’intéresse à des quantités macroscopiques conservées (le volume, la ...

Approximate steady-state solutions for Markov systems based upon the transition-rate matrix deviation concept

Microelectronics Reliability, 1994
Abstract This paper derives an approximate method for solving the steady-state Markov equations. The approximate solutions are determined using the known or easily obtainable solutions of a Markov system whose transition-rate matrix slightly differs from that of the original system.
