Admittance‑Based Two‑Stage Optimisation of GFM‑STATCOM Parameters for Transient Voltage Support in DFIG Wind Farms

IET Generation, Transmission &Distribution, Volume 20, Issue 1, January/December 2026.
This paper builds an admittance model for a DFIG‐STATCOM parallel system. Based on the system, the paper provides a method to optimise the control of the STATCOM， which aims to increase the performance of the system during symmetrical faults .

Transient Energy Shaping Strategy for Grid‐Forming Converters Based on the Port‐Hamiltonian Framework

IET Generation, Transmission &Distribution, Volume 20, Issue 1, January/December 2026.
This study investigates the transient stability of grid‐forming converters (GFMs) in converter‐based grids (CBGs) without main grid support, with emphasis on the impact of current‐limiting control on the stability region. Unlike conventional Lyapunov‐based approaches, which are difficult to construct and extend to new controllers, we propose a Port ...

Optimal Control Strategy for Frequency Support of Energy Storage Doubly‐Fed Condenser Considering Frequency Trajectory Characteristics of Power Systems

IET Generation, Transmission &Distribution, Volume 20, Issue 1, January/December 2026.
This paper proposes a rotor speed‐based frequency trajectory control strategy for ESDFC to tackle frequency stability issues in high‐renewable power systems with reduced inertia. Integrating dual‐objective optimisation and adaptive parameter design, the strategy effectively suppresses the initial RoCoF and frequency nadir deviation without mode ...

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.
