The Advanced Manufacturing Innovation Initiative (AMII), a three-year, $6.3M project, brought together researchers from Sandia, Iowa State University, and TPI Composites [...]

Inter-Agency Agreement Signed between DOE’s Wind and Water Power Program and Carderock

December 3rd, 2014|Categories: Energy, News, News & Events, Partnership, Renewable Energy, Water Power|Tags: , , , , , , , , |

The Department of Energy (DOE) has launched a multiple-year effort to validate the extent to which control strategies can increase the power produced by resonant wave-energy converter (WEC) devices. Many theoretical studies have shown a promise that additional energy can be captured by controlling the power-conversion chains of resonant WEC devices. The numerical models employed in these studies are, however, idealized to varying degrees. The 12.2-million-gallon Maneuvering and Sea Keeping (MASK) Basin at the [...]

Spar-buoy and semi-submersible size comparison over design range. Sandia and the University of Maine recently published a Sandia technical report on floating-platform options for deep-water vertical-axis wind turbines (VAWTs). This analysis uses a 5 MW VAWT topside design envelope created by Sandia to compare floating platform options for each turbine in the design space. The platform designs are based on two existing designs, the OC3 Hywind spar-buoy and Principal Power’s WindFloat semisubmersible. The designs [...]

Sandia Develops Tool to Evaluate Wind-Turbine/Radar Impacts

December 3rd, 2014|Categories: Computational Modeling & Simulation, Energy, News, News & Events, Partnership, Renewable Energy, Wind Energy|Tags: , , , , , , , |

Our nation relies upon a network of radars across the country to support the missions of homeland defense, homeland security, flight safety, and weather forecasting. The air-surveillance environment contains within it clutter, both stationary and moving. Wind turbines present a unique problem in that they can be both stationary and moving clutter and operate with blade tip speeds up to 200 knots, in the same range of aircraft speeds. The DOE and Sandia [...]

Image of a SWiFT rotor wake under uniform inflow conditions constructed from a VWiS large-eddy simulation. One of the primary roles of Sandia’s Scaled Wind Farm Technology (SWiFT) facility will be to conduct detailed experiments on turbine wakes and investigate how those wakes interact with nearby turbines. Although the SWiFT turbines are somewhat smaller than MW-scale turbines being deployed today, Sandia would like the SWiFT turbines, and their wakes, to behave in a [...]

Sandia has developed a mobile acoustic Doppler velocimeter (ADV) system that characterizes inflow and wake flow velocity and turbulence around a vertical axis turbine deployed at the Roza Canal, Yakima, Washington. The ADV was mounted on a hydrofoil (see figure, left-hand panel) and deployed using either an aluminum platform mounted on a bridge (center panel) or using a cableway system (right-hand panel). The acoustic Doppler velocimeter (ADV) probe, mounted on a hydrofoil (left). The [...]

Continuous Reliability Enhancement for Wind (CREW): Project Update

September 23rd, 2014|Categories: Energy, News, News & Events, Renewable Energy, Systems Analysis, Wind Energy|Tags: , , , , , , , , , , , , , , |

During 2013, the CREW team performed an internal reassessment of their effort to identify the benchmark’s value, any data gaps, and opportunities to be better aligned with the wind industry and found that wind-plant owners and operators have been developing in-house reliability-data collection tools with similar goals to the CREW project and that the original CREW strategy has been overtaken by a fast-growing wind industry. However, a national reliability benchmark remains highly desirable for the [...]

Quantifying Offshore Wind Scour with Sandia’s Environmental Fluid Dynamics Code (SNL-­‐EFDC)

September 17th, 2014|Categories: Computational Modeling & Simulation, Energy, News, News & Events, Renewable Energy, Wind Energy|Tags: , , , , , , , , , |

A key risk driver in offshore wind projects is the potentially detrimental interaction between offshore wind substructures/cables and the seafloor. In previous years, Sandia developed methods for evaluating regional sediment stability with the use of combined wave, circulation, and sediment dynamics modeling. Knowledge of sediment stability—not only in the vicinity of an offshore wind deployment, but all the way to the shoreline—can help optimize array layouts and cable routes by identifying seabed locations that are [...]

The Rio Grande River north of Albuquerque, New Mexico. In the majority of western US regions, freshwater availability is a challenging factor for developing new power plants. In some basins, surface and/or groundwater may be available through permitting with the state water-management agency, alternatively water might be purchased and transferred out of its current use to another, or nontraditional water sources can be captured and treated (e.g., wastewater). The relative availability and cost of [...]
