IEEE Std 1547.1-2020 (Revision of IEEE Std 1547.1-2005)

IEEE Standard Conformance Test Procedures for Equipment Interconnecting Distributed Energy Resources with Electric Power Systems and Associated Interfaces


This standard provides tests and procedures for verifying conformance of distributed energy resources (DERs) to IEEE Std 1547™.1 It is recognized that a DER can be a single device providing all required functions or an assembly of components, each having limited functions and capabilities. Components having limited functions and capabilities shall be tested for those functions in accordance with this standard. Conformance may be established through a combination of type, production, and commissioning tests as well as DER Design Evaluations and DER Installation Evaluations. Additionally, conformance to IEEE Std 1547 may require periodic tests.

This standard also includes Annex A, which describes normative test signals and ramp functions used in conducting some tests. Information on where to find the test results reporting template (a separate document) is provided in Annex B. Additionally, Annex C through Annex J provide informative content that may be helpful in implementing this standard, but that is not required to implement the procedures defined in this standard.


This standard specifies the type, production, commissioning, and periodic tests and evaluations that shall be performed to confirm that the interconnection and interoperation functions of equipment and systems interconnecting distributed energy resources (DER) with the electric power system (EPS) conform to IEEE Std 1547, as revised, corrected, or amended.


Distributed energy resources (DERs) shall meet the requirements specified in IEEE Std 1547. Standardized test and evaluation procedures are necessary to establish and verify compliance with those requirements. These procedures shall provide repeatable results and flexibility to accommodate a variety of DER technologies and functions.
