Large-Signal Modeling of Virtual Admittance-Based Grid-Forming Inverter [PDF]

As wind power capacities increase, the decreasing inertia of modern power systems challenges its frequency stability. Unlike traditional grid-following inverters, grid-forming (GFM) inverters can create and stabilize a grid independent of the utility ...

Evaluation of Remotely Sensed Inundation Data Sets to Estimate Flood‐Associated Emergency Department Visits After Hurricane Harvey

GeoHealth, Volume 10, Issue 1, January 2026.
Abstract Floods can increase the risk of adverse health outcomes through multiple pathways, including contamination of food and water. Remotely sensed (RS) inundation extents can help identify regions with expected heightened flood‐related health risks, but variations across inundation data sets and their integration into health risk assessments may ...

Frequency-Voltage Active Support Strategy for Hybrid Wind Farms Based on Grid-Following and Grid-Forming Hierarchical Subgroup Control

CSEE Journal of Power and Energy Systems
The GFL-GFM hybrid wind farm (HWF) combines the voltage source control advantages of grid-forming (GFM) wind turbines (WTs) with the current source control advantages of grid-following (GFL) wind turbines.

A Model Predictive Approach for Enhancing Transient Stability of Grid-Forming Converters

, 2023
A model-based approach for controlling post-fault transient stability of grid-forming (GFM) converter energy resources is designed and analyzed. This proposed controller is activated when the converter enters into the saturated current operation mode. It

Parametric Sensitivity Analysis of a Multi‐Gigawatt Offshore Multi‐Energy System Using Reduced‐Order Models

IET Energy Systems Integration, Volume 8, Issue 1, January/December 2026.
ABSTRACT When multiple grid‐forming and grid‐following converters operate within an offshore energy system (OES), dynamic interactions among them can lead to poorly damped oscillations and potential instability. This paper proposes a computationally efficient reduced‐order state‐space modelling framework for small‐signal stability and parametric ...

Impedance Matching Control of Grid‐Forming Energy Storage Converter for Improving the Stability of the Renewable Energy Stations

IET Energy Systems Integration, Volume 8, Issue 1, January/December 2026.
ABSTRACT Increased penetration of power converters within electrical power systems frequently induces resonance issues, which can often be mitigated by reshaping the output impedance of renewable energy sources (RES). From the perspective of feasibility and cost‐effectiveness, the energy storage converter (ESC), which is already integrated into most ...

Self-Stability and Induced-Stability Analysis for Frequency and Voltage in Grid-Forming VSG System With Generic Magnitude–Phase Model [PDF]

The frequency and voltage stability of grid-forming virtual synchronous generator (GFM-VSG) grid-tied system becomes significant in inertia and damping support when GFM-VSG is attached to the power network. In this article, we propose a generic open-loop

Fractional‐Order Sequence Impedance Modelling and Stability Assessment of Grid‐Connected Virtual Synchronous Generators

IET Generation, Transmission &Distribution, Volume 20, Issue 1, January/December 2026.
This study develops a fractional‐order sequence impedance model for grid‐connected virtual synchronous generators, incorporating realistic broadband characteristics of inductive and capacitive components. Utilising harmonic linearisation and the generalised Nyquist criterion, we demonstrate that optimised fractional‐order models significantly enhance ...
