Project Highlights

Dynamic Contingency Analysis for Cascading Failures, September 1, 2016

The Dynamic Contingency Analysis Tool, or DCAT, uses cascading failure analyses to screen for weak spots on the grid, evolving beyond previous “steady-state contingency analysis” tools to “dynamic analysis” to simulate the sequences of cascading outages.

Mode Meter: Keeping Oscillations in Check, September 1, 2016

Researchers at PNNL joined with colleagues at Montana Tech and the University of Wyoming to develop Mode Meter. This software uses data from advanced sensors—called synchrophasors— placed on power lines and other electrical transmission devices to obtain precise, time-synchronized data about power grid operation.

New Inverter Testing Supports Solar in Hawaii, September 1, 2016

NREL partnered with SolarCity and the DOE Solar Energy Technology Office to quantify the impacts of ground fault and load rejection overvoltage in Hawaii.

NREL + Duke Energy Test Voltage Control for Distributed Solar, September 1, 2016

NREL and partner GE Grid Solutions simulated future circuit operations with a distribution management system provided by Duke, comparing three operating modes: with conventional inverters; with advanced inverters providing local power control; and with advanced inverters coordinated by the DMS to optimize voltage control.

Outsmarting Storms in Chattanooga, September 1, 2016

Through a DOE Smart Grid Investment Grant, the Electric Power Board of Chattanooga secured funding to accelerate the modernization of their power infrastructure.

Eastern Renewable Generation Integration Study, August 1, 2016

NREL convened the Eastern Renewable Generation Integration Study—or ERGIS—a high-performance computing effort for understanding impacts of higher renewable penetrations.

New Jersey TransitGrid Protects Critical Assets, August 1, 2016

Following Superstorm Sandy, rebuild efforts led by rail operators, including the NJ Transit Corporation, focused on protecting transportation infrastructure against physical damage. Recognizing the dependence on electricity supply, NJ Transit Corporation proposed the development of a resilient transportation microgrid called NJ TransitGrid, a first-of-its-kind microgrid capable of keeping the power running during a grid outage.

Power Model Integrator Reduces Forecasting Errors, August 1, 2016

Researchers at PNNL developed a software tool that greatly improves the accuracy of net interchange predictions.  The tool, called the Power Model Integrator, adaptively combines the strengths of different forecasting models continuously and in real time.

Real-Time Path Rating Relieves Grid Congestion, August 1, 2016

In collaboration with partners, researchers at PNNL used high-performance computing techniques to develop a “real-time path rating” software tool that allows operators to maximize the use of today’s transmission assets and tap into unused capacity.

Reforming New York’s Energy Vision, August 1, 2016

Recognizing trends in technological innovation and system security, New York Governor Andrew M. Cuomo established the Reforming the Energy Vision (REV) in March 2015. This new energy initiative includes ambitious clean energy targets.
