The Smart Power Infrastructure Demonstration for Energy Reliability and Security (SPIDERS) Joint Capability Technology Demonstration (JCTD) completed its Phase 1 operational demonstration at Joint Base Pearl Harbor-Hickam in late January 2013. Part of the SPIDERS assessment team scrutinized controller operations, system status, and continuity of operations throughout the demonstration. Their report will focus on system [...]


Sandia, DOE Energy Storage Program, GeneSiC Semiconductor, U.S. Army ARDEC: Ultra-High-Voltage Silicon Carbide Thyristors

Increasing consumer power demand creates numerous challenges for ensuring reliable, stable power for all customers. Many energy generation technologies, particularly renewables, generate direct-current power that must be converted to alternating current before use. Power switches, known as thyristors, perform this conversion and are crucial to a reliable electricity grid. Current switches have been inefficient and [...]

Solar energy is both predictable—the sun rises and sets everyday—and intermittent—a passing cloud can reduce a 1 MW photovoltaic (PV) array from 100% of its power generating capacity to 10% in a matter of seconds. This intermittency limits this renewable-energy (RE) source and how much of it is integrated into today’s electricity grid. To alleviate [...]


Sandia Offers Approach to Help Utilities Understand Effects of PV Variability on the Grid

A report released recently by Sandia National Laboratories, the Electric Power Research Institute (EPRI), and the Georgia Institute of Technology provides a unique approach to help utilities assess the potential effects of high levels of solar photovoltaic (PV) systems on the grid. “Time Series Power Flow Analysis for Distribution Connected PV Generation” demonstrates how quasi-static [...]


Sandia Report Offers Reliable Way to Evaluate Unintentional Islanding Risk

On February 28, 2013, in DETL, Distribution Grid Integration, Energy, Energy Assurance, Energy Surety, Events, Grid Integration, Infrastructure Security, Microgrid, News & Events, Photovoltaic, Renewable Energy, Research & Capabilities, Solar, Solar Newsletter, SunShot

A recently released Sandia National Laboratories report, “Suggested Guidelines for Assessment of DG Unintentional Islanding Risk,” outlines a procedure to help utility distribution engineers determine the risk of unintentional islanding in distributed energy generation installations. By providing a quick and reliable way to identify situations in which such risk is negligible, Sandia’s approach can help [...]
