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.

Sensor Data Identifies Turbine Wake Clustering, Improves Wind Farm Productivity Via Yaw Control

In the Journal of Renewable and Sustainable Energy, researchers describe a real-time method for potentially helping turbine farms realize additional power from the clustering of their turbines. Their method requires no new sensors to identify which turbines at any given time could increase power production if yaw control is applied, and validation studies showed an increase of 1%-3% in overall power gain.

Steering Wind Turbines Creates Greater Energy Potential

For wind farms, it is important to control upstream turbines in an efficient manner so downstream turbines are not adversely affected by upstream wake effects. In the Journal of Renewable and Sustainable Energy, researchers show that by designing controllers based on viewing the wind farm system as a coupled network, it is possible to extract power more efficiently.

Argonne leads creation of definitive valuation guide for pumped storage hydropower

Argonne scientists led four other laboratories in developing definitive guidance on how to value pumped storage hydropower projects. Their efforts resulted in DOE publication of the Pumped Storage Hydropower Valuation Guidebook: A Cost-Benefit and Decision Analysis Valuation Framework. The guide provides an objective, transparent valuation methodology and helps measure both monetary and non-monetary value streams.


Biodiversity Research Institute announces the formation of its new environmental consulting services division—BRI Environmental offering a full suite of services for evaluating and permitting renewable energy development projects, infrastructure projects, marine installations, as well as residential and commercial development.

Argonne and Sentient Science develop game-changing computer modeling program to improve discovery and design of new materials

Researchers collaborated to create a software program to accelerate discovery and design of new materials for applications allowing for a far more comprehensive understanding of materials from atomistic to mesoscopic scale than ever before.

Argonne researchers focus on grid cybersecurity to pave the way for a clean energy future

Distributed energy resources use electronics to communicate with each other or with a control center. Yet this presents opportunities for cyber attacks that could become real threats to the electric power system. Argonne experts are developing ways to protect power systems from these threats before they can occur.
