The effects of electric power lines on the breeding ecology of greater sage-grouse.

open access: yesPLoS ONE, 2019
Anthropogenic infrastructure can negatively affect wildlife through direct mortality and/or displacement behaviors. Some tetranoids (grouse spp.) species are particularly vulnerable to tall anthropogenic structures because they evolved in ecosystems void

Natural Frequency Optimization of Wireless Power Systems on Power Transmission Lines

open access: yesIEEE Access, 2018
Optimizing the natural frequency is crucial for dc-to-load efficient wireless power transfer (WPT) applications on high voltage (HV) power transmission lines. However, a comprehensive optimization approach with the coupling factor and the losses on power

Seismic vulnerability evaluation of power grids in mainland China

open access: yesGeomatics, Natural Hazards & Risk
A refined vulnerability evaluation methodology for substations, transmission lines, and power grids in mainland China is proposed. A database suitable for assessing the vulnerability of power grid facilities in districts (counties) is established.
