Experimental Assessment of Inverter‐Based Frequency Support via Transient Frequency–Power Dynamics

IET Generation, Transmission &Distribution, Volume 20, Issue 1, January/December 2026.
This paper presents a systematic experimental assessment of inverter‐based frequency support based on transient frequency–power dynamics. Grid‐following droop, grid‐forming droop and virtual synchronous machine control are compared under identical laboratory conditions, complemented by an H∞$\mathcal {H}_\infty$‐based matching approach to shape grid ...

Enhanced control strategies for managing frequency fluctuations during deloading of a photovoltaic system

Ain Shams Engineering Journal
Solar and wind power systems are receiving increased attention across multiple nations. Unlike traditional converters, this converter lacks inertia due to the absence of rotating mass, resulting in an overall decrease in grid inertia.

Frequency Ensemble Analysis for ADN‐MG Systems With Heterogeneous DGs

IET Generation, Transmission &Distribution, Volume 20, Issue 1, January/December 2026.
The frequency regulation capability of an ADN‐MG system can be enhanced by exploring the potential of complementary intermittent power outputs of heterogeneous distributed generators. This paper establishes an ensemble equivalent model to analyse the frequency domain of the ADN‐MG system, and the frequency domain of the ADN‐MG system is estimated from ...

Beyond 50 Hz, Unlocking Voltage and Frequency for More Flexible Grids

IET Generation, Transmission &Distribution, Volume 20, Issue 1, January/December 2026.
This paper proposes a vision that redesigns the distribution grid with asynchronous clusters enabled by power‐electronic interfaces as fundamental units, each capable of operating with independent frequency and voltage magnitude, providing bidirectional and controllable power flow. The vision suggests paradigm shifts redefining the roles of voltage and

A Novel Coordinated Control Strategy Between the Grid‐forming SVG Equipped With Supercapacitors and Renewable Energy Gathering Stations to Support Frequency Stability

IET Power Electronics, Volume 19, Issue 1, January/December 2026.
Grid‐forming static var generators (SVG) with supercapacitors and power electronics can provide dynamic reactive compensation and inertia support, but challenges exist in coordinating their inertia support with automatic generation control (AGC) units in renewable energy gathering stations.

A Novel Coordinated Control Strategy for VSG to Enhance Power Tracking Speed Without Degrading Inertia Support Capability

IET Power Electronics, Volume 19, Issue 1, January/December 2026.
ABSTRACT The virtual synchronous generator (VSG), as a representative grid‐forming control method, has become a key technology in distributed renewable energy systems. However, there exists an inherent trade‐off between fast power reference tracking and high virtual inertia support in conventional VSG control.
