Standards Roadmap for the Smart Grid (SGIX) (v2)

in , , , ,

Thanks for all those comments on my earlier post. I have updated the work and am re-posting.

The smart grid is more than improved top down control; it is a grid ready for unreliable energy sources (such as wind, waves, and sun), distributed generation, and Net Zero Energy (NZE) buildings. NZE buildings sometimes buy energy, sometimes sell energy, and energy use balances out over the day, season, or year. The NZE building presents particular problems as it may switch from buying energy one minute, and selling energy the next. Plug-in electric vehicles, whether hybrid or not, present the challenges similar to those of NZE buildings, with the added complexity of mobility. The smart grid requires distributed decision making, distributed responsibility for reliability, and easy interoperability to integrate an ever-changing mix of technologies.

What Standards do we need for the Smart Grid (SGIX)

in , ,

As I do periodically, I have been thinking about what standards we need for the smart grid. The smart grid is more than improved top-down control, it is a grid ready for unreliable energy sources (such as wind, waves, and sun), distributed generation, and net zero energy buildings. Net zero energy buildings are particularly troublesome because from minute to minute, they may be buy power or selling power. The smart grid will be transactional, with each purchase of energy at a market clearing price. The smart grid will be open and transparent, wherein consumers can choose what kind of power to buy, and providers can prove that they are selling the kind of power they promise.

Earlier this week, Alex Levinson referred to the suite of standardds we will need for the smart grid as Smart Grid Information Exchange (SGIX). So what are the standards we need for SGIX?

Energy Interoperability Standards: Smart Buildings, Smart Grid

in , , ,

Earlier this month, Bill Cox of Cox Software Architects proposed the formation of standard committee for Energy Interoperability at OASIS. The core of the proposed work is the definition of XML and Web services interactions for so-called Automated Demand Response, growing out of work at the Lawrence Berkeley National Laboratory Demand Response Research Center. The proposal comes from the context of many discussions in and related to the OpenADR Technical Advisory Group, GridWise Architecture Council, Grid-Interop, the NIST Smart Grid project, and GridEcon (an upcoming conference on the economics of the Smart Grid).

Smart Buildings, Smart Energy, and the Road Ahead

in , , , ,

I arrived in Chicago for the AHR show with the early Sunday morning budget flight crowd. I was not surprised that most of the van worked with HVAC. I was gratified to be recognized by Terry Reynolds of Control Technology. Terry told me that he was using oBIX in his jobs. "We are just starting to crack things open" he observed. We compared notes on projects ranging from the UNC EBMS (Enterprise Building Management System) to the New York City public school energy management system.

He went on to ask me of what is going to drive adoption faster. I think there are five elements of smart energy that are now...
