Energy Surety

Estimating Device or System Probability of Failure

On May 9, 2013, in Analysis, Energy Surety, Facilities, Infrastructure Security, Modeling, Modeling & Analysis, News, News & Events, NISAC

POF Darts is a new algorithm for the QMU problem of estimating device or system probability of failure (POF), e.g., of critical infrastructures in the face of a potentially disruptive event. POF Darts wraps around a computational simulation of a device, evaluating it at particular parameter values, such as uncertain environmental conditions and varying as-manufactured [...]

George Wang, a senior investigator in solid-state lighting science, was invited to speak at the 7th Taiwan Solid-State Lighting (2013 tSSL). The conference was held on March 26th-27th in Taipei, Taiwan. The purpose of tSSL is “to bring together scientists and engineers actively engaged in research, development, and manufacturing on all aspects of Solid State [...]


ECIS-Princeton Power Systems, Inc.: Demand Response Inverter

On March 19, 2013, in DETL, Distribution Grid Integration, Energy, Energy Surety, Facilities, Grid Integration, Infrastructure Security, Microgrid, Partnership, Photovoltaic, Renewable Energy, Research & Capabilities, Solar

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

On March 7, 2013, in DETL, Distribution Grid Integration, Energy, Energy Surety, Facilities, Grid Integration, Infrastructure Security, Microgrid, News, News & Events, Photovoltaic, Renewable Energy, SMART Grid, Solar Newsletter, Systems Analysis, Systems Engineering

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 [...]
