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 ...

IET Generation, Transmission &Distribution, Volume 20, Issue 1, January/December 2026.This paper reviews the common grid‐following (GFL) and grid‐forming (GFM) control principles, technical characteristics, and the limitations of their medium‐voltage direct current (MVDC) applications. In addition, typical switching strategies for GFL and GFM are introduced and analysed. Finally, the applications of MVDC adopting GFL, MVDC adopting GFM,

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 ...

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 ...
