Synchronous Fault Compensator for Voltage Sensorless Grid-Following Power Converters

open access: yes2021 IEEE 12th International Symposium on Power Electronics for Distributed Generation Systems (PEDG), 2021
During the last decade, the penetration of grid-connected RES systems has been in constant increase, forcing those systems interfaced to the electrical grid to improve and design new advanced controllers to maintain the power converter under control. The most extended control for grid-tied inverters is the so-called grid-following control.

An Overview on the Recent Advances of the Voltage Source Converter Control Modes in Terms of their Roles in Transmission Grid Ancillary Services

open access: yesENP Engineering Science Journal, 2022
Voltage Source Converters (VSC) are expected to be one of the major actors in future AC transmission grids. Their role includes the interconnection of renewable energy, from distributed sources such as residential PV to large Offshore Wind Farms (OWF ...

Control of Grid-Following Inverters Under Unbalanced Grid Conditions

open access: yesIEEE Transactions on Energy Conversion, 2020
This paper proposes a new control scheme to eliminate the 3rd harmonic in the output currents of grid-following inverters under unbalanced grid conditions. Unbalanced grids adversely affect the performance of grid-following inverters due to the oscillations appearing on the DC-link voltage with a frequency twice the line frequency.

Contribution of Voltage Support Function to Virtual Inertia Control Performance of Inverter-Based Resource in Frequency Stability

open access: yesEnergies, 2021
Inertia reduction due to inverter-based resource (IBR) penetration deteriorates power system stability, which can be addressed using virtual inertia (VI) control. There are two types of implementation methods for VI control: grid-following (GFL) and grid-

Grid-Forming and Grid-Following Based Microgrid Inverters Control

open access: yesIraqi Journal for Electrical and Electronic Engineering, 2022
Microgrids (ℳ-grids) can be thought of as a small-scale electrical network comprised of a mix of Distributed Generation (DG) resources, storage devices, and a variety of load species. It provides communities with a stable, secure, and renewable energy supply in either off-grid (grid-forming) or on-grid (grid-following) mode.

Internal Induced Voltage Modification for Current Limitation in Virtual Synchronous Machine

open access: yesEnergies, 2022
Virtual inertia control is a methodology to make inverter-based resources (IBR) behave like a synchronous machine. However, an IBR cannot fully emulate the response of synchronous machine because of its low-current capacity. When the inertial response of

Spherical Harmonic Decomposition on a Cubic Grid [PDF]

open access: yes, 1999
A method is described by which a function defined on a cubic grid (as from a finite difference solution of a partial differential equation) can be resolved into spherical harmonic components at some fixed radius. This has applications to the treatment of

Transient Stability of Paralleled Virtual Synchronous Generator and Grid-following Inverter

open access: yesIEEE Transactions on Smart Grid, 2023
<p>The majority of inverter-based resources (IBRs) currently operate as grid-following inverters (GFLIs). These inverters exhibit certain stability issues when integrated in low-strength areas of the grid. To enhance the grid strength in a GFLI-dominant area, virtual synchronous generators (VSGs) are installed.
