Upcoming Webinar: Comparing the Abilities of Energy Storage, PV, and Other Distributed Energy Resources to Provide Grid Services, Monday, March 13, 3:00pm-4:30pm ET

The grid is undergoing a transformation leading to greater utilization of Distributed Energy Resources (DER). DER devices include batteries, PV, and even aggregated hot water heaters or building lighting systems. At the core of this transformation are the services that these DER can provide to the grid. Presently each device type is siloed into its [...]

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

Utility-scale PV systems connected to the transmission network must comply with NERC modeling, data, and analysis standards. WECC’s new “Central Station Photovoltaic Power Plant Model Validation Guideline” helps them with this requirement.

Navy/Marine Engineering Command Visits Sandia

Our nation relies upon a network of radars across the country to support the missions of homeland defense/ security, flight safety, and weather forecasting. The air-surveillance environment contains within it clutter, both stationary and moving. Wind turbines present a unique problem in that they can be both stationary and moving clutter and operate with [...]

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 [...]

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

Different types of parallel arc-faults on the DC side of a PV array. 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 [...]

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. Sandia researcher Vitalie Stavila inserts a substrate patterned with electrodes into a temperature-controlled liquid-phase reactor for depositing MOF thin [...]

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. Glare viewed from the air traffic control tower at Manchester/Boston Regional Airport. SGHAT uses an interactive Google Maps interface together with [...]
