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...

An Evolutionary Composite Services Framework for Energy

in , , , , , ,

Future energy systems must not only support interoperability on operational, e-commerce, and security levels, but they must do so against a background of innovation. New technologies will arrive from innovators who are not traditional energy participants; it must be easy for these innovators to introduce their products and easy to integrate these products into the intelligent grid.

New business models, especially support for distributed generation and the hybrid technologies such as the zero net energy building, will demand new interfaces. These business models require...

SCADA Security, Building Systems, and First Response

in , , , ,
The security of the "internet of Things" and the security of the wider internet are about to collide. The Systems that have been hidden or off line will be on-line. Embedded systems, building systems, power supply and distribution must all change their security model. Eggshell security, the hard shell on the outside and no internal security, will be torn apart not only by the Smart Grid, and all its participants and influencers, but by new models for energy interaction as microgrids, pocket generation, and on-site storage increase the number of participants.
