About the stabilization of the dendritic structure of GG brand copper powder [PDF]

, 2015
In industry copper powder is recieved under constant current load. Surface roughening occurs during evolution of the dendritic particles. It is suggested to create a new impulse of current equal to the initial current density of 3200 A/m2 in order to ...

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 ...

Enhancing Resilience and Efficiency in Low‐Voltage Resistive AC Microgrids Through Distributed Control Strategies

IET Generation, Transmission &Distribution, Volume 20, Issue 1, January/December 2026.
A distributed secondary control strategy for low‐voltage resistive AC microgrids is proposed, where consensus‐based algorithms dynamically adjust both the slope and offset of V‐I droop characteristics. This dual adaptation enables accurate proportional power sharing and effective voltage regulation at the PCC, while ensuring fast transient response and

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 ...
