Active Low‐Voltage Ride‐Through Control Strategy for Wind Turbines to Improve Transient Stability in Power Systems

IET Generation, Transmission &Distribution, Volume 20, Issue 1, January/December 2026.
Based on the characteristic of wind turbine LVRT influencing system power balance, this study proposes a method utilising active LVRT control to achieve transient stability. A transient stability control strategy is developed by integrating active LVRT with deep reinforcement learning while introducing a disturbance‐level‐based coordinated control ...

Improved Phase Comparison Phase‐to‐Phase Distance Protection for Transmission Lines Connected to Energy Storage Power Stations Based on Polarisation Voltage Phase Reconstruction

IET Generation, Transmission &Distribution, Volume 20, Issue 1, January/December 2026.
This paper studies the fault characteristics of the energy storage power station's transmission lines and its influence on the traditional phase comparison distance protection, under different charging and discharging operating conditions. An improved phase comparison distance protection based on polarisation voltage phase reconstruction is proposed ...

Preventive Control Considering Stability Constraints for Repeated Low Voltage Ride Through Events

IET Generation, Transmission &Distribution, Volume 20, Issue 1, January/December 2026.
This paper proposes a voltage stability preventive control strategy that accounts for repeated low‐voltage ride‐through characteristics. The method first partitions the system and constructs a short‐term voltage stability assessment index that effectively incorporates repetitive LVRT events, while offline generating a corresponding set of anticipated ...

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

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 ...
