Automated DR and OpenADR

Automated DR

Fully-automated signaling from a utility, ISO, RTO, or other appropriate entity to provide automated connectivity to customer end-use control systems, devices, and strategies. Does not require full automation on the customer end.

OpenADR

Open and interoperable information exchange model and emerging Smart Grid standard. OpenADR standardizes the message format used for AutoDR so that dynamic price and reliability signals can be delivered uniformly and interoperably among utilities, ISOs, and energy management and control systems. While previously deployed AutoDR systems are automated, they are not standardized or interoperable.

Provides non-proprietary, open, standardized DR communications

Allows electricity providers to communicate DR signals directly to customers

Uses a common language and existing communications (such as the Internet)

OpenADR Schema

OpenADR created own schema – References elements from EI 1.0 – Created own xsd files – Subset of EI standard

EI Standard– Implements more than DR– Market-based implementations exist

OpenADR 2.0– One implementation of DR– More restrictive than EI

OpenADR Standard

Services are limited implementations of what’s offered by Energy Interoperation v1.0– EiEvent, EiOpt, EiReport,

EiRegisterParty

Messages exchanged with services are XML-based, defined by schema

OpenADR schemas validate against Energy Interop v1.0 schemas

Interactions Between VTNs and VENs

OpenADR defines the interactions between Virtual End Nodes (VEN) and Virtual Top Nodes (VTN)

NOTE: VEN and VTN refers to the INTERFACE ONLY and not the machine

DRMS = DR Management System

NGR = Non-generating Resource

GEN = DER = Power Source

EPRI and the OpenADR Alliance

The Alliance’s mission is to foster the development, adoption, and compliance of OpenADR standards through collaboration, education, training, testing, and certification.– Led development of OpenADR Profiles 2.0a and

2.0b

EPRI’s role is to identify and mitigate issues or gaps in the specification that prevent OpenADR from being used in specific use cases identified by project participants– Contributed to:
