Energy Experts Shape Smart Grid at Transactive Energy Conference

December 2014

At the 2nd annual Transactive Energy Conference in Portland, Or., on December 10-11, 2014, PNNL researchers joined nearly 200 other experts from government, industry, utilities, and academia to exchange information about advances in transactive energy concepts, systems and technologies, barriers to market adoption, and related legislative and policy issues.

Transactive energy, as defined by the PNNL-led GridWise® Architecture Council, is “A system of economic and control mechanisms that allows the dynamic balance of supply and demand across the entire electrical infrastructure using value as a key operational parameter.” Transactive energy systems are especially applicable to the integration of the growing number of distributed energy resources. The exchange of information regarding the cost and availability of energy from bulk and distributed resources is balanced with information about needs for electricity to maintain economically efficient and reliable operations at the bulk and local levels of the electric power system.

On Wednesday, several PNNL speakers were featured:

  • Carl Imhoff, electricity infrastructure sector manager, presented a keynote address during lunch on the first day, describing the decade long journey of transactive energy, lessons learned from field demonstrations, and implications of distributed grid operations on traditional utility business models.
  • Jeff Taft, chief architect for electric grid transformation, joined other members of the GridWise Architecture Council in a panel discussion of their roadmap for improving and expanding transactive energy deployment and development.
  • Cristina Marinovici, electricity researcher, discussed how electric customers responded to real-time power pricing during the AEP Ohio-led gridSMART Demonstration Project

    Transactive energy has already been used in the Pacific Northwest, including an advanced version that is part of the Pacific Northwest Smart Grid Demonstration Project. As one example, Portland General Electric’s new grid-scale battery in Salem, Oregon used the project’s transactive communications signal to coordinate its charge and discharge cycles with the grid’s energy supply and demand. The overall demonstration project is nearing completion; representatives from PNNL, the Bonneville Power Administration, and other project partners shared some initial results at the conference. Plans for furthering the progress and utilizing the assets acquired during the project are underway.

    The conference was hosted by the GridWise® Architecture Council and Smart Grid Northwest, with PNNL’s Ron Melton serving as the conference chair. For more information, visit the Transactive Energy Conference website.
