![]() That could open up the utility sector as a new growth market for so-called NoSQL, or object-oriented, database technology. And that task, Taube said, could simply be too much data, moving too fast, for traditional relational database management systems to handle. Actually doing something with that data will require a new level of integration across discrete back-end IT systems, as well as flexibility to adapt to constantly changing sets of real-world conditions - essentially, constantly rewriting the data flows for the grid in near-real time. The study, one of the first fruits of the EPRI/Versant partnership, “shows, in a very simple way, that if you have measurement units in place, they would have given plenty of time to respond in an effective way,” Bert Taube, Versant’s director of business development, said in an interview last week.īut that response only starts with the billions of data points coming in from grid sensors like synchrophasors. The Redwood City, Calif.-based company joined EPRI’s IntelliGrid research program in February, becoming the only object-oriented data management solution provider in a long list of major smart grid vendors working with the utility-funded research group. The statistics come from a recent study by the Electric Power Research Institute (EPRI) and NoSQL database vendor Versant. Increase that to 1,000 synchrophasors, and you’re talking up to 41.5 billion data points, or 402 gigabytes of data, per day - and a lot of that data is flowing into back-end IT systems at the microsecond speed. That involves a lot of new data - up to 6.2 billion data points per day at a size of up to 60 gigabytes with 100 synchrophasors. ![]() In 2006, the DOE and the Federal Energy Regulatory Commission (FERC) recommended that utilities and grid operators install synchrophasor-based transmission monitoring systems to collect the real-time data needed to predict and manage these kinds of problems, in close to real time, to catch the initial errors and fix them before they lead to disaster. ![]() The two-day blackout that cost about $6 billion in lost productivity - and played a part in at least a dozen deaths.įaulty equipment and human error were both to blame, a 2004 Department of Energy task force found. That hot afternoon, a series of overheated power lines sagged into overgrown trees and shut down, triggering a cascading collapse of the grid across eight northeastern states and Canada’s Ontario province. One of the biggest, baddest smart grid data sets out there describes how more than 50 million people lost power in the northeastern U.S. ![]()
