BS IEC 62746 is a series on systems interface between customer energy management system and the power management system is the portion of the system used to connect one system to other systems. BS IEC 62746‑10‑1 specifies a minimal data model and services for demand response (DR), pricing, and distributed energy resource (DER) communications. BS IEC 62746‑10‑1 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.
BS IEC 62746‑10‑1 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. BS IEC 62746‑10‑1 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.
BS IEC 62746‑10‑1 on systems interface between customer energy management system and the power management system is useful for:
Development of the demand response (DR) market has resulted in a transition from manual DR to Open automated demand response in automated DR programs. DR is defined as an action taken to reduce electricity demand in response to price, monetary incentives, or utility directives so as to maintain reliable electric service or avoid high electricity prices. BS IEC 62746‑10‑1 is developed to support common auto-DR programs and energy policy objectives to move toward dynamic markets to improve the economics and reliability of the electricity grid. The recent developments have expanded the use of BS IEC 62746‑10‑1 to meet diverse market needs, such as ancillary services, dynamic prices, intermittent renewable resources, supplement grid-scale storage, electric vehicles, and load as generation.
BS IEC 62746‑10‑1 is a communications data model, along with transport and security mechanisms, which facilitate information exchange between two endpoints, the electricity service provider or DR program operator, and a customer-side resource. It is not a protocol that specifies "bit-structures" as some communications protocols do, but instead relies upon existing open standards such as Extensible Markup Language (XML) and internet protocol (IP) as the framework for exchanging DR signals. In some references, the term "system," "technology," or "service" is used to refer to the features of BS IEC 62746‑10‑1. Using BS IEC 62746‑10‑1 you can specify a minimal data model and services for open automated demand response, pricing, and distributed energy resource (DER) communications.
