Sub‐Synchronous Oscillation in Offshore Energy Islands With MMC‐HVDC Links: Mechanism, Analysis and Mitigation

IET Generation, Transmission &Distribution, Volume 20, Issue 1, January/December 2026.
This paper investigates the small‐signal stability of offshore energy islands interconnected by multiple MMC‐HVDC links and reveals a previously unreported sub‐synchronous oscillation (SSO) mechanism caused by multi‐converter coupling through the offshore AC network.

Transient characteristics and adaptive fault ride through control strategy of DFIGs considering voltage phase angle jump

Journal of Modern Power Systems and Clean Energy, 2017
Wind power in China has experienced fast development in recent years. However, areas rich in wind power resources are often far away from loads centers, which leads to weak connection between wind turbines and power grid.

Short‐Circuit Current Analysis of Grid‐Connected Inverters: An Analytical Approach Using Hardware Natural Response and Control Superposition

IET Generation, Transmission &Distribution, Volume 20, Issue 1, January/December 2026.
This paper proposes a closed‐form analytical framework predicting the sub‐cycle transient peak currents of grid‐following and grid‐forming inverters during short‐circuit faults. The method uniquely decouples the fault current into a hardware natural response and a control‐commanded response, enabling rapid estimation of instantaneous initial peaks ...

Addressing Distance Relay Mal‐Operation in Low‐Inertia Grids: A PLL‐Informed Power Swing Assessment

IET Generation, Transmission &Distribution, Volume 20, Issue 1, January/December 2026.
A key advantage of the proposed approach is its independence from PLL control settings, relying solely on locally measured electrical quantities, which ensures robust, fast, and practical implementation in existing commercial distance relays. ABSTRACT The increasing penetration of inverter‐based resources (IBRs) has substantially reduced system inertia

Optimizing Fault Ride-Through of DGs in Distribution Networks to Preserve Recloser-Fuse Coordination

IEEE Access
Fuse saving protection is usually applied in distribution networks, through auto-reclosing, to prevent fuse burning under transient faults. The modern fault ride-through (FRT) standards, which require distributed generators (DGs) to remain connected ...

Data Centre Model for Transient Stability Analysis of Power Systems

IET Generation, Transmission &Distribution, Volume 20, Issue 1, January/December 2026.
This paper proposes a dynamic load model for Data Centers (DCs) to accurately simulate their impact on power system transient stability. The model uniquely incorporates key DC components, including Uninterrupted Power Supplies (UPS), cooling systems modeled as induction motors, and specific load patterns for Artificial Intelligence (AI) and batched ...

Improving fault ride‐through capability for doubly‐fed induction generator based on improved system structure and corresponding control scheme

IET Energy Systems Integration
Although there are many methods to improve the fault ride‐through (FRT) capability of doubly‐fed induction generator (DFIG) systems at present, each method has its shortcomings, especially the applicability under different voltage dips (VDs), so an ...

Enhancing Grid Resilience via Bidirectional Adaptive Control of Distributed Energy Resources Under Composite High‐Impact Contingencies

IET Generation, Transmission &Distribution, Volume 20, Issue 1, January/December 2026.
This work proposes the Bidirectional Adaptive Frequency Support (BAFS) framework to mobilise latent behind‐the‐meter residential energy storage for bidirectional primary frequency regulation without physical power export. By abstracting battery charging as ‘dynamic absorption’ and load offsetting as ‘virtual injection’, BAFS structurally bypasses zero ...

Enhanced Phase‐to‐Phase Distance Protection for AC Lines With Power‐Electronics‐Interfaced Sources

IET Generation, Transmission &Distribution, Volume 20, Issue 1, January/December 2026.
This paper proposes an adaptive enhanced phase‐comparison distance protection (PCDP) strategy to address the maloperation risks caused by high penetration of power electronics‐interfaced sources (PEIS). Unlike the conventional scheme with a fixed operating boundary, the proposed strategy dynamically adjusts the protection zone, effectively capturing ...
