LVRT Capacity Enhancement of DFIG Based Wind Farms by Controller Based Auxiliary Devices [PDF]

, 2016
Wind energy is one of the most prominent sources of renewable energy. However, subjected to the high penetration of wind energy into existing power grids, stability and smooth operation of electric power system is at stake due to the vulnerability of the

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.

Admittance‑Based Two‑Stage Optimisation of GFM‑STATCOM Parameters for Transient Voltage Support in DFIG Wind Farms

IET Generation, Transmission &Distribution, Volume 20, Issue 1, January/December 2026.
This paper builds an admittance model for a DFIG‐STATCOM parallel system. Based on the system, the paper provides a method to optimise the control of the STATCOM， which aims to increase the performance of the system during symmetrical faults .

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 ...

A study on the negative sequence current injection during LVRT of IBRs

RE&PQJ
Low Voltage Ride Through (LVRT) behaviour of Inverter Based Resources (IBR) during asymmetrical grid faults is dictated by the requirements of Grid Code (GC) at the Point of Common Coupling (PCC) of the renewable energy plants. Earlier GCs demanded only positive sequence current injection, which gave freedom to inverter manufacturers to implement ...
