How Do Wind Turbines Respond to Winds, Ground Motion During Earthquakes?

Wind power has experienced fast growth within China during the past decade, but many wind farms are being built within regions of high seismic activity. In Journal of Renewable and Sustainable Energy, researchers present their work exploring the dynamic behaviors of wind turbines subjected to combined wind-earthquake loading. The group discovered that changes in the wind increase and decrease the response amplitude of the wind turbine under weak and strong earthquakes, respectively.
