How wind turbines react to turbulence: Study provides new method to achieve more consistent electricity production

The output of wind turbines can rise or fall by 50% in a matter of seconds. Such fluctuations in the megawatt range put a strain on both power grids and the turbines themselves. A new study by researchers from the University of Oldenburg and the Sharif University of Technology in Tehran presents a new stochastic method that could help to mitigate these sudden swings and achieve a more consistent electricity production.

Libya dam collapse: Engineering expert raises questions about management

More than 11,000 people have been killed and tens of thousands are missing following the catastrophic collapse of two dams in the eastern Libyan city of Derna. The dam collapse came after an extreme storm, Storm Daniel, slammed into the north African country. The Conversation Africa’s Moina Spooner asked water resources and engineering expert Nadhir Al-Ansari, who has researched the design and safety of dams, to provide insights into the disaster.
