Sandia Labs participates in DOE Executive Summit on Marine and Hydrokinetic Research and Development

Sandia’s Water Power Technologies Department participated in the Executive Summit on Marine and Hydrokinetic Research and Development, sponsored by the U.S. Department of Energy Office of Energy Efficiency & Renewable Energy (EERE) on March 2, 2016 in Washington, D.C. Vince Neary gave an overview of Sandia’s facilities, capabilities, and innovations; Kelley Ruehl (pictured, second from left) showcased [...]

Sandia Develops Stochastic Production Cost Model Simulator for Electric Power Systems

Sandia has developed a software toolkit that uses stochastic programming to perform power system production cost model simulations. Named PRESCIENT, the software produces probabilistic forecasts automatically from deterministic historical forecasts for load, solar, and/or wind power production and their respective actuals, using a technology known as epi-splines. An example of a probablistic solar forecast [...]

New CREW Database Receives First Set of Data

The CREW public benchmark represents analysis of US wind fleet performance based on aggregated fleet reliability data. Sandia’s Continuous Reliability Enhancement for Wind (CREW) project has received its first large set of data, which reassessed its data-collection efforts to target wind-farm owner/operators that have in-house reliability data collection tools. After a lengthy negotiation [...]

Aerodynamic Wind-Turbine Blade Design for the National Rotor Testbed

The NRT blade shape as viewed from the tip and at an elevation angle of 30° above the suction surface. Sandia has designed a new wind-turbine blade for the National Rotor Testbed (NRT) project and for future experiments at the Scaled Wind Farm Technology (SWiFT) facility with a specific focus on scaled wakes. [...]

Sandia Researchers Win Best Paper Award from the American Institute of Aeronautics and Astronautics

Researchers Joe Oefelein and Guilhem Lacaze (both in Sandia’s Reacting Flow Research Dept.) won the American Institute of Aeronautics and Astronautics’ (AIAA’s) best paper award for their work on scramjet engine simulations. The paper, “A Priori Analysis of Flamelet-Based Modeling for a Dual-Mode Scramjet Combustor,” was a collaboration with Jesse Quinlan and James McDaniel (Univ. [...]

CRF Researchers Are Source for 2015 QTR Sidebar Content

On September 10th, Energy Secretary Ernest Moniz released the second Quadrennial Technology Review (QTR 2015), which examines the most promising research, development, demonstration, and deployment (RDD&D) opportunities across energy technologies to effectively address the nation’s energy needs. Specifically, this analysis identifies the important technology RDD&D opportunities across energy supply and end-use in working toward a [...]

Wave-Energy/-Device Modeling: Developing A 1:17 Scaled Model

Many theoretical studies show that additional energy can be captured through control of the power-conversion chains (PCCs) of resonant wave-energy converter (WEC) devices. The numerical models employed in these studies are, however, idealized to varying degrees. The objective of the Resilient Nonlinear Controls (RNLC) project is to validate the extent to which control strategies, given [...]

Government-Industry Radar/Airspace Listening Session at WindPower2015

Representatives from the federal agencies participating in the Wind Turbine Radar Interference Mitigation (WTRIM) Working Group held a special Government-Industry Radar/Airspace Listening Session at the American Wind Energy Association AWEA WindPower 2015 event in Orlando, Florida. The event was well attended by more than 50 persons (other than the panel members). The panel consisted of [...]

Upcoming Release of the University of Minnesota’s Virtual Wind Simulator

Large-eddy simulation (LES) of wind farms with wind-turbine parameterization is emerging as a powerful tool for improving existing wind farm performance and lowering maintenance costs—and assessing the potential sites for installing wind farms. Sandia is working with the University of Minnesota (UMN) St. Anthony Falls Laboratory to document and prepare UMN’s offshore version of the [...]
