Sandian Contributes to Western Electricity Coordinating Council Photovoltaic Power Plant Model Validation Guideline

As part of the Western Electricity Coordinating Council’s (WECC’s) Modeling and Validation Work Group, Sandia researcher Ryan Elliott (in Sandia’s Electric Power Systems Research Dept.) recently contributed to an update to WECC’s Central Station Photovoltaic Power Plant Model Validation Guide­line.

The document provides photovoltaic (PV) plant owners and transmission planners with best prac­tices for model validation […]

Navy/Marine Engineering Command Visits Sandia

Steven Chung, Naval Facilities Engineering Command, Southwest (NAVFAC SW),1 Dwight Deakin, Naval Air Systems Command (NAVAIR),2 Melanie Anderson (NAVAIR PAX River), and David Weir, Marine Corps Installations–West (MCIWEST-MCB Camp Pendleton)3 visited Sandia June 24–25 to discuss several renewable energy/related topics:

wind-turbine/radar interaction,
photovoltaics (PV), and
cybersecurity as it relates to renewable energy.

They also discussed potential collaboration with Sandia […]

Sandia Researcher Recognized at SunSpec Alliance Annual Meeting

Sandia solar researcher Jay Johnson (in Sandia’s Photovoltaics and Distributed Systems Dept.) attended the SunSpec Alliance Annual Member’s Meeting in San Francisco last Spring and received the 2015 SunSpec McCulloch-Pitts Award in recognition of “innovation, collaboration, and general technical excellence in the area of distributed energy resource control automation.”

The award acknowledged Johnson’s collaborative research as […]

Sandia Research on PV Arc-Fault Detection Submitted for US Patent

Sandia National Laboratories/Tigo Energy researchers recently submitted an application for a US patent related to research on arc-fault detection and circuit interruption in solar photovoltaic (PV) systems. Sandia’s patent-pending methods, filed as Identifying an Arc-Fault Type in Photovoltaic Arrays, allow AFCIs to distinguish between series and parallel faults.

The 2011 National Electrical Code® requires PV DC […]

PV Plant Performance Technical Briefing Published in PV Power Tech

The state of the art in PV system monitoring is relatively simplistic, relying either on comparisons of outputs between various parts of the system (e.g., inverters) or on an evaluation of a performance metric that normalizes output to available irradiance and other environmental conditions. However, neither of these methods is very effective in discovering the source […]

Combining ‘Tinkertoy’ Materials with Solar Cells for Increased Photovoltaic Efficiency

Sandia researchers have received a $1.2M award from the DOE’s SunShot Initiative to develop a technique that they believe will significantly improve photovoltaic (PV) materials efficiency and help make solar electricity cost-competitive with other energy sources.

The work builds on Sandia’s recent successes with metal-organic framework (MOF) materials by combining them with dye-sensitized solar cells (DSSCs). DSSCs, […]

Solar Glare Hazard Analysis Tool Available for Download

Sandia developed the Solar Glare Hazard Analysis Tool (SGHAT), a web-based tool that predicts energy production and the potential for solar glare and ocular impacts from an array of photovoltaic (PV) panels.

SGHAT uses an interactive Google Maps interface together with a few user-specified parameters such as orientation and tilt of the PV panels to quickly

locate […]
