Title: Standard for Smart Energy Profile Protocol

Scope: This standard defines an application profile that provides an interface between the smart grid and users. It enables management of the end user energy environment, including demand response, load control, price communication, distributed generation, energy storage, and electric vehicles, as well as the support of additional commodities, including water, natural gas, and steam. This standard defines the mechanisms for exchanging application messages, the exact messages exchanged including error messages, and the security features used to protect the application messages. This standard focuses on a variety of possible architectures and usage models, including direct communications between a service provider and consumers/prosumers, communications within a premises network, and communications between a service provider and an aggregator. Lastly, this standard sources elements from many existing standards, including IEC 619686 and IEC 61850, and follows a RESTful architecture utilizing widely adopted protocols such as TCP/IP and HTTP. In addition, it supports all of the needs of IEEE Std 1547™-2018. This revision maintains backward compatibility with IEEE Std 2030.5™-2018, except for elimination of the requirements for mandatory DERControl modes, while providing an expanded feature set.
