Interconnection Standards Development

DOE works with representatives of both the public and private sectors to support the development of standards for distributed generation. The development of such national standards will ensure that distributed power products meet minimum requirements for performance, safety, and maintenance and will significantly advance the commercialization of these new technologies.

Research thus far has focused on two standards. The first, IEEE 1547, Standard for Interconnecting Distributed Resources With Electric Power Systems, provides a uniform standard for the interconnection of distributed resources by detailing requirements related to the performance, operation, testing, safety, and maintenance of interconnection. This standard was approved by the IEEE Standards Board in June 2003.

In addition to the basic standard incorporated under 1547, several additional activities have begun to further develop the interconnection provisions contained in 1547 to make them more useful.

The second major standard is an update to UL 1741, Standard for Inverters, Converters, and Controllers for Use in Independent Power Systems. This standard will incorporate IEEE 1547 to produce a testing standard to be used by this nationally recognized testing body for evaluating interconnected products for safety and interconnection performance requirements.
