scope:

This part of IEC 62746-10, OpenADR 2.0 (this document), specifies a minimal data model and services for demand response (DR), pricing, and distributed energy resource (DER) communications. This document can be leveraged to manage customer energy resources, including load, generation, and storage, via signals provided by grid and/or market operators. These resources can be identified and managed as individual resources with specific capabilities, or as virtual resources with an aggregated set of capabilities.

This document specifies how to implement a two-way signaling system to facilitate information exchange between electricity service providers, aggregators, and end users. The DR signalling system is described in terms of servers (virtual top nodes or VTNs), which publish information to automated clients (virtual end nodes, or VENs), which in turn subscribe to the information.

This document provides application-level service communication that can be used to incentivise a response from a customer-owned DER. Price and DR signals over the internet allow indirect control of customer-owned devices that otherwise would not be available.

This document's services are independent of transport mechanisms. For the purposes of interoperability, this document provides basic transport mechanisms and their relevant interaction patterns to address different stakeholder needs. In addition, this document specifies cyber security mechanisms required for data confidentiality, integrity, authentication and message-level security, in order to provide non-repudiation and mitigation of cyber security risks.

The services make no assumption of specific DR electric load control strategies that can be used within a DR resource or of any market-specific contractual or business agreements between electricity service providers and their customers.

This document provides a clear set of mandatory and optional attributes within each of the services to meet broader interoperability, testing and certification requirements. All necessary XML schema are included in Annex E.
