Virtual LIDAR Model Helps Researchers Plan for Wake Steering Experiment at SWiFT

A team of researchers at Sandia National Laboratories and the National Renewable Energy Laboratory (NREL) are planning a critical experiment at Sandia’s Scaled Wind Farm Technology (SWiFT) Facility to investigate the use of wind turbine yaw control to direct wakes, a promising approach to increase power production in wind plants. During the multi-month field campaign, [...]

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 [...]

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 [...]

New Small Business Voucher Pilot Opens

The highly anticipated Department of Energy (DOE) Small Business Vouchers (SBV) pilot opens for business today. Through the pilot, small businesses can apply to access the Department’s world-class facilities and an enterprise of more than 10,000 leading scientists and engineers at the National Renewable Energy Laboratory and Lawrence Berkeley, Oak Ridge, Pacific Northwest, and Sandia national laboratories. [...]

Sandia Wake-Imaging System Successfully Deployed at Scaled Wind Farm Technology Facility

The Sandia Wake-Imaging System (SWIS) was deployed for a full-scale field demonstration at the Sandia Scaled Wind Farm Technology (SWiFT) facility in Lubbock, Texas, in July. This successful field demonstration was a culmination of over 3 years of technical development; more than a year of safety, environmental, and regulatory approvals; and the efforts of 20 [...]
