Modeling and Control of a Multi‐Energy Microgrid With Wind LVRT and Battery Pre‐Synchronization Strategy

Energy Science &Engineering, Volume 14, Issue 1, Page 266-280, January 2026.
This study establishes a hybrid microgrid model integrating a Doubly Fed Induction Generator (DFIG), a photovoltaic (PV) array, and a battery energy storage system, and proposes a coordinated control framework. The DFIG regulates DC‐bus voltage through the grid‐side converter and performs maximum power tracking via the rotor‐side converter, while the ...

Multi‐Layer MTDC Protection: Design and Simulation Assessment

IET Generation, Transmission &Distribution, Volume 20, Issue 1, January/December 2026.
This study proposes a novel multi‐layer protection architecture for multi‐terminal DC systems that separates fault current‐limiting and interruption functions. By combining a thyristor‐based fault current limiter with an active resonance circuit breaker, the scheme significantly reduces peak fault currents and di/dt stress, enabling a more compact ...

Mechanism and suppression of breaking overvoltage of DC circuit breakers

High Voltage
The occurrence of breaking overvoltage in a DC circuit breaker (DCCB) poses a potential threat to the safe operation of a DC grid. Based on the structure of the ±10 kV three‐terminal DC distribution network, this paper sets up the medium‐voltage DCCB and
