Summary

In order to address the need for taller wind turbine towers, DOE (Department of Energy) released an FOA (Funding Opportunity Announcement) on Taller Hub Heights to Access Higher Wind Resources and Lower Cost of Energy. The principal investigator (PI) submitted a successful concept paper to the DOE to facilitate the completion of the final phase of the Hexcrete tower concept developed at Iowa State University. This new concept was developed using the PI’s professorship’s funds and the Iowa Grow Value Fund— and 1) uses modular components that can be prefabricated locally and transported using standard trucks; 2) increases design life to 40-50 years instead of the current 20-25 years; 3) uses readily available materials to minimize weight and transportation costs; and 4) facilitates foundation options that can be easily decommissioned. By overcoming the challenges associated with steel tubular wind turbine towers, the Hexcrete concept is designed to dominate tower height in the 100 to 140m range.

Hexcrete towers with increased heights will 1) access high wind speeds and steadier wind conditions; 2) increase wind production time; 3) leverage opportunities to harvest energy in regions where favorable wind conditions exists above 100 m; and 4) lower wind energy cost. The impact of successfully completing the Hexcrete tower will strengthen wind energy production in Iowa, reduce wind energy cost, and increase Iowa job markets in wind energy, precast fabrication and commercial transportation.

Innovative Dual-Rotar Wind Turbine Designs to Improve Wind Farm Efficiency

Grant Renewable Energy Feb. 2014 — Jan. 2015 Ames, Iowa
Summary:

We seek opportunity grant funds from the IEC to explore a novel dual-rotor wind turbine (DRWT) concept to improve aerodynamic efficiency of isolated turbines as well as wind farms. The DRWT concept uses a secondary (likely smaller), aerodynamically optimized rotor to recover losses near the hub (root) of the main rotor, and to promote rapid [...]

Summary

We seek opportunity grant funds from the IEC to explore a novel dual-rotor wind turbine (DRWT) concept to improve aerodynamic efficiency of isolated turbines as well as wind farms. The DRWT concept uses a secondary (likely smaller), aerodynamically optimized rotor to recover losses near the hub (root) of the main rotor, and to promote rapid mixing of turbine wake thus reducing wake losses in wind farms. Through variable operation of the secondary rotor, the velocity shear in the wake can be tailored to amplify mixing during conditions when wake/array losses are dominant. The increased power capacity can also be used to extract energy at wind speeds below the current cut-in speeds of single-rotor turbines. We are working proactively to seek external funding from federal agencies such as NSF and DoE as well as wind energy industries such as Vestas, GE, and Siemens to support our efforts to develop innovative DRWT systems. If funded, the results derived from this project will significantly strengthen our planned external proposals.

Realistic Simulation of a Wind Farm Unit for Energy Production Optimization

Grant Renewable Energy Jan. 2014 — Aug. 2014 Iowa City
Summary:

An area of growing interest in wind energy production is the collective optimization of wind farm design and operation, considering the interaction among turbines, with the objective of increasing production efficiency. It is estimated that between 10 to 40 % of wind energy production and revenue is lost due to complex wind plant interaction, losses [...]

Summary

An area of growing interest in wind energy production is the collective optimization of wind farm design and operation, considering the interaction among turbines, with the objective of increasing production efficiency. It is estimated that between 10 to 40 % of wind energy production and revenue is lost due to complex wind plant interaction, losses that could be reduced by optimization of design and operation of the plant as a whole. Recently, the US Department of Energy (DOE) commissioned the Scaled Wind Farm Technology (SWiFT) facility to study those interactions. Our objective is to write software capable of reproducing farm-wide dynamics that can be used to aid design and operation of current and future wind farms, both onshore and offshore. We are seeking funds to develop a proof-of-concept demonstration with 10 to 20 fully resolved wind turbines, which will help obtain external funding to complete this software, primarily from DOE, but also from the National Science Foundation (NSF).
