Virtual inertia emulating in power electronic–based power systems

open access: yes, 2021
The concept of virtual inertia is adopted from the moment of inertia of synchronous generator (SG) rotating masses. The conventional power systems profit from the inertial function of numerous existing SGs to solve or improve the frequency challenges, e ...

Adaptive Virtual Inertia for AC Grids Connected to MT‐HVDC Grid by Considering DC Voltage Stability

open access: yesIET Renewable Power Generation
The growing integration of power electronics converters (PECs) and multi‐terminal high voltage DC (MT‐HVDC) grids within the power system decreases the system's inertia.

Energy Storage Sizing for Wind-Storage Frequency Regulation: Kinetic Energy Recovery and Secondary Frequency Drop Suppression

open access: yesEnergies
High wind power penetration aggravates power system inertia scarcity, and wind turbines switching to MPPT mode after virtual inertia support induces secondary frequency drop (SFD), impairing grid frequency stability.

Demo 02-13 Inertia Cylinder

open access: yes, 2001
A heavy cylinder hangs by a thin rope from a rigid frame. A second identical thin rope is attached to the bottom of the cylinder, and a short metal rod is attached to the bottom end of the lower rope, as shown in Figure 1.

Enhanced Virtual Inertia Controller for Microgrid Applications

open access: yes, 2023
Unlike Synchronous Generators (SGs), Virtual Synchronous Generators (VSGs) inertia is not fixed once it is manufactured and only has an upper limit defined by its energy storage components. In this paper, a novel Enhanced Virtual Inertia Controller (EVIC)

Decoupling Design Method for DC Virtual Inertia and Voltage Loop Stability Margin

open access: yesCSEE Journal of Power and Energy Systems
Implementation of large virtual inertia with high stability margin is a significant challenge for DC microgrid systems. In this paper, a filter time constant, a new degree of freedom, is utilized to enhance voltage loop stability and its relationship ...

Moving the Weber fraction: the perceptual precision for moment of inertia increases with exploration force [PDF]

open access: yes, 2012
How does the magnitude of the exploration force influence the precision of haptic perceptual estimates? To address this question, we examined the perceptual precision for moment of inertia (i.e., an object’s ‘‘angular mass’’) under different force ...

Virtual Inertia Planning for Enhancing Grid Stability in Low‐Inertia Systems

open access: yesIET Energy Systems Integration
ABSTRACT The global power grid is undergoing a significant transition with the increasing integration of renewable energy sources (RESs). This shift, characterised by a decline in conventional synchronous generators and a rise in inverter‐based RESs, has resulted in reduced grid inertia, posing substantial challenges to frequency ...
