Sandia Report Presents Analysis of Glare Impacts of Ivanpah Solar Power Site

The Ivanpah Solar Electric Generating System (ISEGS) consists of three 459-ft-tall power towers and over 170,000 reflective heliostats with a rated capacity of 390 MW. The California Energy Commission (CEC) has received numerous pilot and air traffic controller glare-impact reports. The situation is serious because pilots report that they cannot “scan the sky in that direction […]

Sandia Wins Award for Best Poster at 40th IEEE Photovoltaic Specialist Conference (PVSC)

  Sandia researcher Jay Johnson (in Sandia’s Photovoltaic & Distributed Systems Integration Dept.) and a collaborating team from Texas A&M University were recognized at the 40th Institute of Electrical and Electronics Engineers (IEEE) PVSC held in Denver, Colorado, on June 8–13, 2014, winning the event’s Best Poster award for “Evaluation Method for Arc Fault Detection […]

Sandia Completes Hydrostructural Analysis of Ocean Renewable Power Company’s TidGen® Turbine

Sandia performed an independent hydrostructural analysis of the Ocean Renewable Power Company (ORPC) TidGen® turbine, with a focus on the bolted-joint connections. Sandia’s CACTUS hydrodynamics software was used to predict dynamic loads on the turbine, and these loads served as input to structural dynamics analysis, performed using Abaqus finite-element analysis (FEA) software. The analysis examined […]

The Influence of Rotor Blade Design on Wake Development

The National Rotor Testbed (NRT) includes research to quantify the degree to which the blade design load distribution influences the rotor near- and mid-wake velocity deficits and fluid structures. Wind-plant performance and the effects of turbine–turbine interaction have been identified as the primary research topics for the NRT blades. The wake deficit and fluid structures […]

Understanding Seasonal Effects of WEC Operation using the SNL-SWAN Wave Model Application

Sandia researchers are investigating the seasonal effects of a wave-energy converter (WEC) array on nearshore wave propagation using SNL-SWAN. WECs were simulated as obstacles with frequency-dependent transmission coefficients that were determined based on the incoming wave height and period. The research team created frequency distributions of seasonal wave parameters (significant wave height, peak wave period, […]
