Transactive Control 101

What is it?

– Transactive control is a distributed method for coordinating responsive grid assets wherever they may reside in the power system.

Incentive and feedback signals

– The incentive signal sends a synthetic price forecast to electricity assets

– The feedback signal sends a consumption pattern in response to the incentive.

An Incentive Signal

Predict and share a dynamic, price-like signal—the unit

cost of energy needed to supply demand at this node using

the least costly local generation resources and imported

energy. May include

– Fuel cost (consider wind vs. fossil vs. hydropower generation)

– Amortized infrastructure cost

– Cost impacts of capacity constraints

– Existing costs from rates, markets, demand charges, etc.

– Green preferences?

– Profit?

– Etc.

Example “Resource Functions”: Wind farm, fossil generation, hydropower, demand charges, transmission constraint, infrastructure, transactive energy, imported energy

7

A Feedback Signal

Predict and send dynamic feedback signal—power

predicted between this node and a neighbor node based on

local price-like signal and other local conditions. May

include

– Inelastic and elastic load components

– Weather impacts (e.g., ambient temperature, wind, insolation)

– Occupancy impacts

– Energy storage control

– Local practices, policies, and preferences

– Effects of demand response actions

– Customer preferences

– Predicted behavioral responses (e.g., to portals or in-home

displays)

– Real-time, time-of-use, or event-driven demand responses alike

– Distributed generation

Example “Load Functions”: Battery storage, bulk inelastic load, building thermostats, water heaters, dynamic voltage control, portals / in-home displays

Transactive Node Inputs & Outputs

The system is distributed, predictive, scalable, and its signals track the energy that it represents.

Progress Towards Project Objectives

12

To Recap – Regional Benefits

• Opportunity to leverage smart grid assets installed by regional utilities using an innovative incentive structure

• Extend and validate the concepts demonstrated in Oly-Pen project – Flexible approach to integrating BPA’s and Utility’s operational

objectives and responsive resources

– Standardized, interoperable approach to facilitate broad application

• Prove and refine the transactive approach – Gather regional cost-benefit information

– Understand scale-up challenges and opportunities

• Continue the region’s legacy of national leadership in power system innovation

13

2015 and beyond

• At the end of the demo project:

– ~ 100 Megawatts of distributed responsive assets engaged

– Transactive control validated as a means of balancing

intermittent renewable resources

– Base of smart grid equipment installed at 11 utilities

• Beyond the demo project

– Scale up to engage additional responsive assets

– Transition from R&D to operations

– Operationalize for balancing authorities (regional value)

– Further deployment with energy service providers to enhance

value to their operations (local value)
