IEEE 1547.2-2023 PDF

This guide provides the technical background, rationale, and guidance to support the application of the substantially revised IEEE Std 1547-2018, IEEE Standard for Interconnection and Interoperability of Distributed Energy Resources with Associated Electric Power Systems Interfaces. The document will describe how the requirements and default settings specified in IEEE Std 1547-2018 have been carefully chosen to balance distribution and bulk system needs for increasing penetration of DERs. It further enhances the understanding of IEEE Std 1547-2018 by addressing certain DER integration issues that are not fully addressed by the base standard, e.g., reclosing coordination and limitation of overvoltage in the Area EPS.

The guide will address: (1) the concept of the newly introduced performance categories and their assignment to specific DERs by an Authority Governing Interconnection Requirements (AGIR); (2) the new requirements for voltage and reactive power control, frequency control, response to abnormal conditions including ride-through; (3) the flexibility provided by the newly introduced ranges of adjustability for control settings as well as for voltage and frequency trip settings to fully exploit the revised IEEE 1547’s potential and to account for specific system characteristics; (4) the interoperability and communication interface requirements; and (5) the test and verification practices, including design and as-built installation evaluations for utility-scale DERs, that were not included in the 2008 version of the standard. Presented in the document are technical descriptions and schematics, applications guidance, and interconnection examples to enhance the use of IEEE Std 1547-2018.

This guide facilitates the use of the substantially revised IEEE Std 1547-2018 by educating relevant stakeholders about its technical background and by providing guidance for its application in practice.

Revision Standard – Active. Technical background and application details to support understanding of IEEE Std 1547™- 2018 are provided. The guide facilitates the use of IEEE Std 1547-2018 by characterizing various forms of distributed energy resource (DER) technologies and their associated interconnection issues. It provides background and rationale of the technical requirements of IEEE Std 1547-2018. It also provides tips, techniques, and common practices to address issues related to DER project implementation. This guide is intended for use by engineers, engineering consultants, and knowledgeable individuals in the field of DERs. The IEEE 1547 series of standards is cited in the Federal Energy Policy Act of 2005, and this guide is one document in the IEEE 1547 series.
