Analysis of Subsynchronous Control Interaction of a Grid Forming Inverter

IEEE Power & Energy Society General Meeting
The grid forming inverter (GFM) is considered a key technology to solve the issues of inverter-based resource (IBR)-rich grids. Many previous studies have discussed the advantages of GFM over grid following inverter (GFL), but there has been insufficient

Current-Controlled Synchronverter: A Grid Fault Tolerant Grid Forming Inverter

IEEE transactions on industrial electronics (1982. Print)
A synchronverter (SV) equipped with an output admittance synthesizer is modified to avoid the usual transient instability of grid forming inverters in presence large grid disturbances, keeping the injected currents at safe values.

Unified Voltage Control for Grid-Forming Inverters

IEEE Transactions on Industrial Electronics
In this article, we propose a unified voltage control for grid-forming inverters, which enables to flexibly synthesize six commonly used voltage control methods through a universal and simple structure. The unified control scheme is composed by three loops, i.e., the voltage magnitude control, the virtual impedance control, and the voltage-reference ...

Grid-Forming Inverter Primary Control Using Robust-Residual-Observer-Based Digital-Twin Model

IEEE Transactions on Industrial Informatics
Grid-forming (GFM) inverters with inductor–capacitor (LC) filters are used to interface distributed generation with the grid. However, the GFM inverter systems are prone to incipient multiplicative faults due to the inherent parameter drift phenomenon of

Safe Reinforcement Learning for Grid-forming Inverter Based Frequency Regulation with Stability Guarantee

Journal of Modern Power Systems and Clean Energy
—This letter investigates a safe reinforcement learning strategy for grid-forming (GFM) inverter based frequency regulation. To guarantee stability of the inverter based resource (IBR) system under the learned control policy, a model based reinforcement ...

Grid Forming Inverter as an Advanced Smart Inverter for Augmented Ancillary Services in a Low Inertia and a Weak Grid System Towards Grid Modernization

Clean Technology
Grid dynamics and control mechanisms have improved as smart grids have used more inverter-based renewable energy resources (IBRs). Modern converter technologies try to improve converters’ capacities to compensate for grid assistance, but their inertia ...

Observer‐based residual‐driven dynamic compensation strategy for performance improvement of grid‐forming inverter

International journal of circuit theory and applications
Grid‐forming (GFM) inverters offer stable frequency support for microgrid systems, even in the absence of synchronous generators. However, the GFM inverters have low inertia and vulnerability to system uncertainties and external disturbances.

Large-Signal Stability of Phase-Balanced Equilibria in Single-Phase Grid-Forming Inverter Systems

IEEE transactions on power electronics
This article explores the setup where large numbers of single-phase grid-forming inverters with droop control across distribution networks self-organize into a stable and balanced system with $120^\circ$ phase offsets across aggregates in the absence of ...
