IEEE 1815.2-2025

This document establishes a Standard Profile for communications with distributed energy resources (DERs) using IEEE Std 1815™ [Distributed Network Protocol (DNP3)]. This profile consists of a high-level data model for DER communications, based on selected data objects from International Electrotechnical Commission (IEC) 61850-7-420:2021 mapped to a fixed list of DNP3 data points. It also specifies the data objects needed for many DER and inverter-base resource (IBR) functions found in IEEE Std 1547™-2018, IEEE Std 2800™-2022, and IEEE Std 1547.9™-2022, as well as additional functions needed for storage systems. In addition, it specifies a mapping to detailed equipment-related data objects. The profile is provided in both a written and an electronic format (Profile Companion Data Point Tables) for ease of implementation.

The data model defined in this standard permits a utility to communicate with DER sites supplied by different DER manufacturers, while those DER manufacturers can communicate with different utilities using this standardized profile. These DER sites can comprise either a plant controller, which can manage multiple DER units, or DER controllers, which each manage a single DER unit. In addition, because the model underlying this profile comes from IEC 61850-7-420:2021, a utility using this profile can communicate using DNP3 and yet be easily integrated with an IEC 61850 network by means of a gateway (i.e., using IEEE Std 1815.1™-2015).

New IEEE Standard - Active. A standard profile for communications with distributed energy resources (DERs) using IEEE Std 1815™ [Distributed Network Protocol (DNP3)] is established. A high-level data model for DER communications, based on selected data objects from International Electrotechnical Commission (IEC) 61850-7-420:2021 mapped to a fixed list of DNP3 data points, comprises the profile. The data objects needed for many DER and inverter-base resources (IBRs) functions, including those in IEEE Std 1547™-2018, IEEE Std 2800™-2022, and IEEE Std 1547.9™-2022, as well as additional functions needed for storage systems, are also specified. In addition, a mapping to detailed equipment-related data objects, including meters, DER units, inverters, and batteries, is provided. The profile is presented in both a written and an electronic format (IEEE 1815.2 Profile Companion Data Point Tables) for ease of implementation.
