Smartgrid Basics: The Supply Side Problem

in , , , ,

Last week the Smartgrid-discuss group opened up within OASIS, introducing power grid technologies to the architects of e-commerce and internet security standards. Some of the latter are trying to understand the problem, and learn the jargon. I wrote this as one of a series of posts introduce the issues in a simplified, almost cartoon form.

The North American power grid is the world’s largest robot. It was imagined in the 30’s, designed in the 50’s and has been built out and patched ever since. Some very bright people have done extraordinary things to retrofit the system with digital descendants of the original analog controls. It is very much less stable...

Whither Grid Standards

in , , , , ,

On last Friday’s phone call about advancing the OpenADR specification to a national and perhaps international standard, we agreed to continue the discussion in an open forum at the OASIS site (www.OASIS-Open.org). OASIS, or the Organization for the Advancement of Structured Information Standards, has long been the home for the underpinnings of e-commerce, for web security, and for service oriented architecture. OASIS is also home to a number of domain-specific standards, such as LegalXML, Open Office, and OpenDocs as well as the foundational web services registry UDDI (Universal Description, Discovery, and Integration).

OpenADR (Automated Demand Response) is a California developed specification developed for...

EBMS Takes its First Steps

in , , ,

I have written before of UNC’s Enterprise Building Management System (EBMS). EBMS talks to legacy systems in more than a 100 buildings on the UNC campus. EBMS uses a half dozen variants of web services to monitor and operate building systems using nearly every brand and every internal protocol. All data is normalized and brought into an industry standard database, currently we are adding 42 million transactions a day to that database.

Phase II of EBMS is finishing up before the end of the year. The system is going through...

To Market, To Market to Buy a Fat Watt

There is a strong tug of war, not only in the buildings to grid (B2G) arena, but in all others, about whether GridWise is about controlling gizmos or about interactions between economic agents. One is paving interstates along the old cow-paths, and one is laying out a city. When you lay out a city, you never know what markets and neighborhoods will actually develop.

Those who have worked long in utilities or in building systems have a deep impulse toward the perfecting old models of control rather than laying out the market rules for transacted energy. Like a dog to his vomit...
