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 ...

Value‐Based Reinforcement Learning for Inter‐Area Oscillations Mitigation in PV‐Integrated Power Systems

IET Generation, Transmission &Distribution, Volume 20, Issue 1, January/December 2026.
Enhanced critic‐only DQN with smoothing enables continuous SVC control for damping inter‐area oscillations. The state selection via participation and residue analysis captures critical key modes. Orthogonal array efficiently tunes hyperparameters with low cost.

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 ...
