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-Developed LED Pulser Delivers Laser-Like Performance at Fraction of the Cost

The high-brightness, rapidly pulsed, multicolor light-emitting diode (LED) driver delivers lighting performance that exceeds that of conventional (laser/arc-light) sources for scientific, industrial, or commercial uses at a fraction of the cost. “I had the idea a few years ago to see if high-powered multicolored LEDs could be pulsed rapidly by an electronic circuit to produce [...]

Sandia Assists NASA in Understanding Launch-Area Accidents

Curiosity’s multi-mission radioisotope thermoelectric generator on Mars. Some NASA spacecraft, those which operate on the surface of other planets or are too far from the sun, require the use of radioisotope power systems (fueled with plutonium dioxide) to produce electricity and heat. In the unlikely event of an early launch accident, these DOE-provided [...]

University of Wisconsin–Sandia Team Awarded SunShot CSP: APOLLO Funding

With recently awarded funding from the US Department of Energy SunShot Initiative’s CSP: APOLLO Program (Concentrating Solar Power: Advanced Projects Offering Low LCOE Opportunities), Sandia is working with a team led by the University of Wisconsin–Madison to evaluate the potential for significant improvements in the commercial viability of supercritical carbon dioxide (sCO2)/Brayton-cycle power conversion as [...]

Natural Energy Laboratory of Hawaii Authority Partners with Sandia to Install Aquion EES Demo

The Natural Energy Laboratory of Hawaii Authority (NELHA) and Sandia have signed an MOU to implement electrical energy storage systems (ESSs) in renewable-energy projects at their Hawaii Ocean Science and Technology (HOST) Park. Aquion Energy battery module installed at NELHA. Hawaii’s innovative green economic development park plays a significant role in Hawaii’s growth [...]

Sandia’s Supercritical Carbon-Dioxide/Brayton-Cycle Laboratory Signs Important MOU with Industry Partners

Sandia and eight other companies and research organizations* will collaborate to advance a distributed power system that can produce cleaner, more efficient electricity. The memorandum of understanding (MOU) focuses on developing an energy-conversion system based on supercritical carbon dioxide (sCO2)/Brayton-cycle technology. Gary Rochau, manager of Sandia’s Advanced Nuclear Concepts Dept. said sCO2/Brayton cycle technology could [...]

Stion Commissions PV System at Sandia Regional Test Center

Stion PV system installed and the Sandia RTC site. Thin-film solar module manufacturer Stion has commissioned a 12 kW fixed latitude ground-mounted photovoltaic (PV) system at the DOE’s New Mexico Regional Test Center (RTC), located at Sandia. The system will be monitored and tested to collect a range of data related to the [...]
