P825 is a standard for ‘transactive technologies’ that the IEEE is developing to allow utilities to deal with the growing numbers of point of supply.
A September 11 article by associate editor Jennifer Delony at Renewable Energy World quotes Shawn Chandler, a director in Navigant’s Global Energy practice, describing how utilities are having to deal with an exponentially growing number of points of control on the supply side, compared to the relative handful of points they had only to think about for decades on the supply side. Transactive energy is the term that has emerged for that new style of control systems. “Within a TE system,” the article explains, “a network allows communication between all points of supply and demand, creating an environment of interoperability in which every point can exchange energy information and basically discuss in real time (or near real time) the value of energy at any given point in time or space.” Chandler is chair of the IEEE Power & Energy Society Smart Buildings, Loads and Customer Systems technical committee, which manages a working group for P825 — Meshing Smart Grid Interoperability Standards to Enable Transactive Energy Networks. The IEEE’s guide will outline the options for TE systems, and make recommendations for how to think about those options, he said.
