Hierarchical Response Control Method for Voltage Support in DFIGs Considering Fatigue Loads

IET Renewable Power Generation, Volume 20, Issue 1, January/December 2026.
This paper proposes a hierarchical response control (HRC) method to address the increased fatigue load on wind turbines during reactive power support for grid voltage stability. By establishing a fatigue sensitivity model and dynamically adjusting control parameters, the method optimally allocates reactive power while avoiding critical shaft ...

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 ...

Assessment of Post‐Fault Voltage Recovery in IBRs‐Dominated Grids: Evaluating the Role of Grid‐Forming Converters

IET Renewable Power Generation, Volume 20, Issue 1, January/December 2026.
Unlike grid‐following (GFL) converters, grid‐forming (GFM) units can emulate the behaviour of synchronous generators (SGs) by establishing grid voltage and frequency autonomously, enhancing both steady‐state performance and dynamic response during disturbances.

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 ...

An Overcurrent Suppression Strategy for Distributed Photovoltaic Inverters Under Unbalanced Faults Based on Adaptive Linear Active Disturbance Rejection Control

IET Smart Grid, Volume 9, Issue 1, January/December 2026.
After distributed photovoltaic (PV) systems are connected to the distribution network, the overcurrent problem caused by transient faults instantaneously threatens the safety of PV inverters and other equipment. This paper proposes a comprehensive control method that combines active‐loop adaptive linear active disturbance rejection control (A‐LADRC ...

Enhancing Fault Ride‐Through Capability of a High‐Voltage Power Grid Using Solar PV–Battery Assisted Auxiliary Support

International Journal of Energy Research, Volume 2026, Issue 1, 2026.
High penetration of inverter‐based renewable energy sources introduces dynamic stability challenges in high‐voltage power systems, particularly under severe fault conditions. This study proposes a renewable‐integrated resilience enhancement framework for the Bibiyana 400/230 kV power hub in Bangladesh to ensure uninterrupted supply to critical 1.2 MW ...

Optimal Linear Protection Scheme of Inverter‐Based Distributed Energy Resources: Meeting Fault‐Ride‐Through Requirement

International Journal of Energy Research, Volume 2026, Issue 1, 2026.
This paper presents a new two‐stage protection strategy for active distribution networks that not only addresses selectivity constraints along protected lines but also incorporates fault‐ride‐through (FRT) requirements of inverter‐based distributed energy resources (IBDERs). The proposed coordination strategy (PCS), which distinguishes it from previous
