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 ...

Effect of Secondary Fluorescence in Thin‐Film Thickness on Compositional Determination Using Electron Probe Microanalysis

X-Ray Spectrometry, Volume 55, Issue 1, Page 184-189, January/February 2026.
ABSTRACT Unlike bulk analysis, thin film compositional analysis necessitates considering substrate effects, such as secondary fluorescence induced by x‐rays generated in the substrate and backscattered electrons. Several methods have been proposed to address these challenges.

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
