The target of smart grid communications, particularly in collaborative
energy space, should always be the microgrid. Some microgrids may contain a single home, or commercial building, or and industrial site—those are irrelevant details. Microgrids have a number of systems inside them that must work within the economic environment of that microgrid—and I am thinking of old economics, before the distinction of economics and ecosystem arose. Some microgrids may have a single entity inside, say a legacy BAS (Building Automation System), but the unitary microgrid is merely an artifact of...

An Evolutionary Composite Services Framework for Energy
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...
Distributed Generation and Lightweight Integration
Distributed generation is a big part of the anticipated new grid. Distributed generation refers to having many small sources of power on the grid. A traditional power company can own distributed generation or someone else, perhaps the building owner, can own it.
Wayne Longcore has described distributed generation today as akin to the early days of personal computing. The big centrally managed power plants have the role of the mainframe, the site where all real power generation occurs. Pocket generation plants, including solar generation on household roofs, are akin to the poorly networked early microcomputers, only able to get on-line with great difficulty, and unable to...
BIM, Services, and Emergency Response
The Building Information Model (BIM) comprises a family of standards, including the three dimensional building model, that compose a comprehensive description of a building. It is an oft hoped desire that the BIM, perhaps working through a mythical BIM server, be accessible to improve situational awareness by emergency first responders
One barrier for this BIM/Emergency management information exchanges is that BIM does not, by and large, define real service mapping. Chemicals and supplies may stored by room number. Ventilation may be by zones established long before the room numbering. Missing people may be...
