Controller design and analysis for grid-forming inverter [PDF]

open access: yes, 2023
When grid-connected inverters significantly outnumber synchronous generators, there is a need for the "grid-forming" inverters to establish the constant voltage amplitude and frequency.

Equivalent Active Distribution Networks Considering Grid Forming Converters

open access: yes, 2021
S.527-531Converters connected to distribution networks play an increasingly important role in the generation mix. Especially grid forming converters providing inertia to the system are vital to handle critical events in a converter dominated system. Thus,

Grid forming H control for HVDC diode rectifier-connected wind power plants [PDF]

open access: yes, 2023
[EN] Grid forming controllers need to operate with a large variation of grid parameters and grid structure, for instance, during black-start operation, connection to HVDC diode rectifiers, etc.

A Comparison of Grid-Forming and Grid-Following Control of VSCs

open access: yes, 2020
Variable renewable energy sources are today increasingly integrated in the power system as a step towards the renewable society. The large-scale introduction of converter-based energy sources brings challenges in terms of reduced damping to the power system due to the reduced number of synchronous generators.

Simulation-based study of novel control strategies for inverters in low-inertia system: grid-forming and grid-followings [PDF]

open access: yes, 2022
The transition towards a 100% converter-based grid has as consequence the constant reduction of the mechanical inertia. Two different kind of devices will be taken into consideration, grid-following and grid-forming devices; the first ones are based on ...

Grid-forming and Grid-Following Dual-Mode Switching Strategy Based on APS-IPSO for Grid-Forming Energy Storage [PDF]

open access: yesDianli jianshe
[Objective] Addressing the challenge that grid-forming energy storage converters,operating in a single mode,struggle to adapt to variations in grid short-circuit ratio and complex fault disturbances,this paper proposes a dual-mode switching strategy ...

Grid-forming frequency shaping control

open access: yesCoRR, 2020
As power systems transit to a state of high renewable penetration, little or no presence of synchronous generators makes the prerequisite of well-regulated frequency for grid-following inverters unrealistic. Thus, there is a trend to resort to grid-forming inverters which set frequency directly. We propose a novel grid-forming frequency shaping control

Design, Control and Testing of a Modular Multilevel Converter with a Single Cell per Arm in Grid-Forming and Grid-Following Operations for Scaled-Down Experimental Platforms

open access: yesEnergies, 2022
Modular multilevel converters (MMC) can be used in several applications, especially (but not only) in high-voltage direct current (HVDC) and STATCOM.
