Unlike ubiquitous axial-flow turbines, cross-flow turbines have rotation axes perpendicular to the flow they sit in. This study presents a control scheme that optimizes blade angular velocity as a function of blade position with no extra degrees of freedom, yielding a 59% increase in power output.
Further global deployment of wind energy, both onshore and offshore, will depend on its future costs. Wiser et al. report the results of a survey of 163 leading experts on the possibilities of cost reduction and technological advancements by 2050.
Increasing generation of clean energy from wind resources will help China meet its 2030 energy-mix target and combat climate change. Davidson et al. model the wind energy generation potential of China, estimating a grid-integrated potential of 2.6 PWh per year in 2030.
Persistent and significant curtailment has cast concern over the prospects of wind power in China. A comprehensive assessment of the production of energy from wind has identified grid-integrated wind generation potential at 11.9–14% of China's projected energy demand by 2030.
China has the largest installed capacity of wind farms, yet its wind energy electricity output is lower than that of other countries. A new analysis of the relative contributions of the factors influencing China's wind sector could help policy makers prioritize solutions.
