IEEE P1547.1a

Amendment Standard - Active - Draft.
The type, production, commissioning, periodic tests, and evaluations that shall be performed to confirm that the interconnection and interoperation functions of equipment and systems interconnecting distributed energy resources with the electric power system conform to IEEE Std 1547 are specified in this standard.

This standard integrates clarifications and corrections identified in the extensive additions to UL 1741 3rd Ed. Supplement SB that incorporated test procedures in IEEE 1547.1-2020.
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.
