High Voltage, EarlyView.ABSTRACT The alternate arm converter (AAC) is one of the most efficient multilevel topologies based on voltage source converters (VSCs), which has recently gained attention in various applications, particularly in high voltage direct current (HVDC) systems.

High Voltage, EarlyView.ABSTRACT To effectively suppress transient overvoltages in HVDC systems, the design and experimental validation of a multi‐module series controllable arrester are presented. The voltage‐limiting performance, series voltage equalisation capability, and robustness under fault conditions in high‐voltage scenarios require further research.

High Voltage, EarlyView.ABSTRACT Amid the ongoing global energy transition, the short‐circuit ratios of AC power grids are continuously decreasing. Grid‐forming voltage source converter‐based high voltage direct current transmission (GFM VSC‐HVDC) systems have therefore come to the forefront of attention.

When is the bait worth the risk? A mechanistic model of a compensatory ecological trap in seabirds
Functional Ecology, EarlyView.Read the free Plain Language Summary for this article on the Journal blog. Abstract Ecological traps occur when organisms preferentially select habitats that reduce fitness. In seabird–fishery systems, fishery‐derived trophic subsidies can increase foraging success, reinforce habitat preference and indirectly enhance reproductive output or recruitment,

From Tap Water Access to Income‐Generating Work Time: Evidence From Rural China
Australian Journal of Agricultural and Resource Economics, EarlyView.ABSTRACT This study examines whether household tap water access affects income‐generating work time among employed rural adults in China. While existing studies have mainly examined the effects of improved water access on employment participation, off‐farm transition and household income, this paper focuses on the intensive margin of labour supply ...
