Adaptive Inertia Controller for Grid-Forming Converters

IFAC-PapersOnLine
This paper presents an adaptive control technique for grid-forming converters to enhance power quality and frequency stability while providing inertial behavior. Using the virtual synchronous generator model, the approach emulates traditional synchronous machines operation but mitigates instability caused by high inertia values.

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

, 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.

Adaptive model predictive control for grid‐forming converters to achieve smooth transition from islanded to grid‐connected mode

IET Generation, Transmission & Distribution, 2023
One of the main capabilities of grid‐forming converters is the ability to operate in both islanded and grid‐connected modes. The grid‐forming converters work autonomously and behave as an AC voltage source when they are isolated from the bulk power ...

An Overview of Grid-Forming Control for Wind Turbine Converters

IECON 2021 – 47th Annual Conference of the IEEE Industrial Electronics Society, 2021
Wind turbine converters (WTCs) with grid forming (GFM) control can contribute to voltage and frequency support in the power system, by emulating synchronous machine (SM) dynamics, provided that there are sufficient buffers. Over the past few years, several control algorithms have been developed for the GFM operation of WTCs.
