IEEE 1547

IEEE 1547 ("Standard for Interconnecting Distributed Resources with Electric Power Systems") is a standard of the Institute of Electrical and Electronics Engineers meant to provide a set of criteria and requirements for the interconnection of distributed generation resources into the power grid.

Purpose

"This document provides a uniform standard for interconnection of distributed resources with EPSs. It provides requirements relevant to the performance, operation, testing, safety, and mainenance of the interconnection."

With the increased adoption of distributed resources in the present and future, a set of standards regarding their usage in the grid become increasingly important for the overall reliability, safety, and cost. Furthermore, the lack of a concrete national standard was seen as a roadblock to the implementation of new distributed generation projects. The standard is intended to be universally adoptable, technology-neutral, and cover distributed resources as large 10 MVA.

Development

In early 1999, the IEEE approved the undertaking of P1547. With the support of the United States Department of Energy, the project was initiated on a fast-track basis, which would halve the usual development time. The draft standard was revised 10 times, before P1547/Draft 11 was approved with a 91% vote in February 2003. It was then approved by the IEEE Standards Board on June 12, 2003, and received an ANSI designation on October 20, 2003.cite web

Energy Policy Act of 2005

“Interconnection services shall be offered based upon the standards developed by the Institute of Electrical and Electronics Engineers: IEEE Standard 1547 for Interconnecting Distributed Resources With Electric Power Systems, as they may be amended from time to time.”

The Energy Policy Act of 2005 established IEEE 1547 as the national standard for the interconnection of distributed generation resources.
