Examining the relationship between wind turbine blade performance and tip vortex behaviour in the wake [PDF]
, 1997 This paper details the results of laboratory tests on a model wind turbine rotor at the University of Edinburgh and examines tip vortex behaviour which questions the assumptions of current rotor performance prediction codes.

Energy Science &Engineering, EarlyView.Three‐turbine guided Savonius arrays installed along highway corridors extract up to 697 J under multi‐vehicle wake conditions when spaced 12 rotor diameters apart—68% more than compact arrangements. Guide vanes boost output by 80–120%, and interior turbines respond most strongly to spacing, governing overall array performance. ABSTRACT Highway‐induced

National Policy Coherence Counts for Reducing Inequality in Global Climate and Development Agendas
Sustainable Development, EarlyView.ABSTRACT International institutions promote policy coherence as crucial to the effective and fair implementation of global sustainability agendas, though the evidence for its benefits is slim. We present here the first systematic cross‐country dataset on the consequences of national government efforts to promote policy coherence for vulnerable groups ...

Bursting Oscillation Characteristics and Improved AHODFC for DFIG and PMSG Combined Wind Farm
Energy Internet, EarlyView.ABSTRACT Bursting oscillations occur in DFIG and PMSG combined wind farm under external disturbances and lead to the instability problems. To reveal the bursting oscillation characteristics and develop a suppression method, a fast‐slow dynamics analysis method and an improved adaptive high‐order differential feedback controller (AHODFC) based on ...

Differences in cluster and internal wake effects from mesoscale and large-eddy simulations off the US East Coast [PDF]
Wind Energy ScienceMesoscale simulations are increasingly used to estimate wake effects within and between large wind farms, despite limited validation for large-scale wake effects. This study evaluates the capabilities and limitations of mesoscale simulations in capturing

Large‐Scale Applications of Plasma Technologies: Progresses and Challenges
High Voltage, EarlyView.ABSTRACT Plasma technologies convert electrical power into energetic electrons, ions, reactive species, radiation and heat, thereby breaking through the bottleneck of purely thermal or chemical routes and bringing impressive changes to our world. This roadmap reviews the progress and challenges of plasma technologies from a large‐scale and application ...
