Scope |
This
standard establishes criteria and requirements for interconnection of
distributed resources (DR) with electric power systems (EPS). The
USA Federal Energy Policy Act of 2005 calls for state commissions to consider
certain standards for electric utilities. Under Section 1254 of the act:
"Interconnection services shall be offered based upon the standards
developed by IEEE 1547 as may be amended from time to time." |

Purpose |
The technical specifications for, and testing
of, the interconnection and interoperability between utility electric power
systems (EPSs) and distributed energy resources (DERs) are the focus of this
standard. It provides requirements relevant to the performance, operation,
testing, safety considerations, and maintenance of the interconnection. It
also includes general requirements, response to abnormal conditions, power
quality, islanding, and test specifications and requirements for design,
production, installation evaluation, commissioning, and periodic tests. The
stated requirements are universally needed for interconnection of DER,
including synchronous machines, induction machines, or power
inverters/converters and will be sufficient for most installations. The
criteria and requirements are applicable to all DER technologies
interconnected to EPSs at typical primary and/or secondary distribution
voltages. Installation of DER on radial primary and secondary distribution
systems is the main emphasis of this document, although installation of DERs
on primary and secondary network distribution systems is considered. This
standard is written considering that the DER is a 60 Hz source. |

Status |
Initially published and designated as an ANSI American
National Standard in 2003. It was reaffirmed in 2008 and amended in 2014. A full revision was published
in 2018. Amended April 2020 to revise the ranges of
allowable trip clearing time settings in Table 13. Revision
approved on 3/24/22. Publication expected shortly. |
