Higher‐Order Statistics Based Pilot Protection Scheme for Wind Farm Transmission Line Connected to VSC Station

IET Generation, Transmission &Distribution, Volume 20, Issue 1, January/December 2026.
This paper analyses the distribution of fault current samples for both external and internal faults conditions and quantifies the differences in the features by using the third‐order cumulant and kurtosis. On this basis, a pilot protection scheme was proposed for transmission lines wind farm transmission line connected to VSC station.

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

Wind–Storage Coordinated Control Strategy for Suppressing Repeated Voltage Ride-Through of Units Under Extreme Weather Conditions

Energies
In practical engineering, large-scale wind power integration typically requires long-distance transmission lines to deliver power to load centers. The resulting weak sending-end systems lack support from synchronous power sources.

Mitigating Grid Stability Risks From Large AI Data Centres: A Three‐Mode Supervisory Control Framework for Centralized UPS Systems

IET Generation, Transmission &Distribution, Volume 20, Issue 1, January/December 2026.
A three‐mode supervisory control framework for centralized data centre UPS systems mitigates the grid stability risks posed by large AI facilities during transmission faults. The framework coordinates current‐limited reactive‐priority allocation, a minimum‐draw policy to limit aggregate load withdrawal and rate‐limited post‐fault recovery, extended to ...

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 ...
