Research on the impact of grid-connected offshore wind farms on transient overvoltage and characteristics of harmonic resonances

Zhejiang dianli, 2023
Grid-connected offshore wind farms are likely to cause harmonic resonances in the power system that jeopardize the safe operation of the power grid. To this end， the impact of grid-connected offshore wind farms on the transient overvoltage and harmonic ...

Stabilizing Magnesium Anodes in Rechargeable Magnesium Batteries via Fluorinated Cyclic Ether Electrolyte Additive

Advanced Energy Materials, EarlyView.
A fluorinated cyclic ether, FDOL, is shown to stabilize Mg metal anodes by tuning Mg2+ solvation of the G2 electrolyte. The G2‐FDOL electrolyte suppresses passivation and thick, diffusion‐blocking Mg deposits, enabling more uniform Mg plating/stripping and sustained interfacial reactions.
