Blackout prevention effort launched as anniversary looms

10.08.2004


As the dog days of summer approach, the electrical grid feels the heat, but a new integrated data network may help the aging transmission system weather the season without another massive blackout like the one experienced over much of the Eastern United States and Canada last August.



The Eastern Interconnection Phasor Project will "go live" this summer providing the first real-time, system-wide data to utilities and transmission operators within the Eastern power grid.

"If this system had been in place last year, it may have helped system operators take steps to avoid the August 14 blackout," said Matt Donnelly EIPP project lead at the Department of Energy’s Pacific Northwest National Laboratory.


PNNL manages the project for DOE as part of the Consortium for Electric Reliability Technology Solutions. CERTS members also provide technical support to an independent EIPP Work Group – a collaboration of utilities, system operators, vendors and power system reliability councils working together to put the integrated network in place.

"The project is about gathering and sharing information to provide complete coverage of the power grid in the eastern U.S.," said Donnelly. With each incremental addition to the EIPP network, the equipment and software that has been installed will provide operators with a big picture of the grid over the eastern half of the country, referred to as the Eastern Interconnection.

Even though the transmission system is interconnected to route electricity between utilities, information has not been efficiently shared between those organizations. As noted by the U.S.-Canada Power System Outage Task Force on the August 2003 blackout, there has been "no consistent means across the Eastern Interconnection to provide an understanding of the status of the power grid outside of a control area."

"If operators can see a disruption or failure occurring elsewhere in the region, they can take actions that will potentially prevent a cascading loss of power from one system to the next," said Mike Ingram of the Tennessee Valley Authority. "They may be able to reroute transmissions or bring extra power generation on-line."

To get this data, new measurement technologies employing satellite-based time clocks are being installed at key locations on the grid to measure power flows in real time. The precise time clocks along with sophisticated signal processing allow the meters to provide more information than can be derived from traditional instruments. EIPP participants believe the additional information can be used to help improve grid reliability.

Data concentrators then collect and integrate the precision data and disseminate it to participants, while software analysis tools make sense of the real-time monitoring.

DOE began working with major Eastern Interconnection utilities and independent system operators to develop a monitoring system in the fall of 2002 and began installing equipment in the fall of 2003. The project builds on PNNL’s 10-years of experience developing a similar measurement and analysis system for the Bonneville Power Administration and utilities in the Western United States.

Initially, control centers near St. Louis; Columbus, Ohio; Chattanooga, Tenn.; New Orleans and Schenectady, New York, will be linked through the EIPP and will start sharing information this month.

The EIPP project is expected to cover and connect most major eastern U.S. corridors by the end of 2005. Together, participating utilities have invested about $1 million toward this effort and DOE has provided about $750,000.

"DOE and the utilities are aggressively responding to recommendations in the blackout report and we’re expecting that the EIPP will play a key role in preventing a repeat of last summer’s blackout," said Donnelly.

Utilities participating in Phase One of EIPP include Ameren, American Electric Power, Entergy, the Midwest ISO, the New York ISO with the New York Power Authority, and the Tennessee Valley Authority.

Im Focus: Exotic quantum states made from light: Physicists create optical “wells” for a super-photon

Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.

Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...

Im Focus: Circular RNA linked to brain function

For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.

While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...

An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.

The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...

Im Focus: Scientists shine new light on the “other high temperature superconductor”

A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.

Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...

Im Focus: Scientists improve forecast of increasing hazard on Ecuadorian volcano

Researchers from the University of Miami (UM) Rosenstiel School of Marine and Atmospheric Science, the Italian Space Agency (ASI), and the Instituto Geofisico--Escuela Politecnica Nacional (IGEPN) of Ecuador, showed an increasing volcanic danger on Cotopaxi in Ecuador using a powerful technique known as Interferometric Synthetic Aperture Radar (InSAR).

The Andes region in which Cotopaxi volcano is located is known to contain some of the world's most serious volcanic hazard. A mid- to large-size eruption has...
