1 Transactive Control in Electricity Delivery Ron Melton Battelle, Pacific Northwest Division

2 Taxonomy of Device Controls Passive device state determined only by consumer demand (e.g., thermostat setpoint) Active device state also influenced by external signal (e.g., price) Interactive information about consumer demand (home, away) is sent so price can be set Transactive information about device internal state (on, off) is sent so price can be set

3 Purpose of Transactive Control Determine signals that optimizes allocation of scarce resources Time-varying value of (constrained) supply Incorporates time-varying value of demand response Addresses 3 major distribution issues: Load growth, distributed resource control, demand response

4 Pacific Northwest Demonstration Project What: $178M, ARRA-funded, 5-year demonstration 60,000 metered customers in 5 states PL EL AV FH Why: Quantify costs and benefits UW Central Ben NW Develop communications protocol MF Develop standards PGE Facilitate integration of wind and other renewables LV Who: Led by Battelle and partners including BPA, 11 utilities, 2 universities, and 5 vendors Key Demand Response Energy Storage Renewables Integration Distributed Generation Grid Friendly Appliance Tech/Data Testing IF

5 Primary Project Objectives Goals: Facilitate the use of load as an active resource for the management of the grid. Validate new smart grid technologies and inform business cases. Quantify smart grid costs and benefits Advance interoperability standards and cyber security approaches for transactive control Integrate rapidly expanding portfolio of renewable resources Regional effort extensible to large portions of the United States Objectives: Manage peak demand Facilitate integration of wind and other renewables Address constrained resources Select economical resources Improve system efficiency Improve system reliability Load Management Conservation Voltage Reduction Distributed generation

6 Transactive Control The Single Signal Ultimately represent the needs of the system at any one location at any point in time Automated based on user input Influenced by: Generation available Transmission needs, congestion, and availability Distribution needs, congestion, and availability System emergencies System stability needs Utility objectives such as generation source preferences End user preferences that inform consumption needs
