IEEE publishes standard revision for interconnection and interoperability of distributed energy resources (DER) with Associated Electric Power Systems Interfaces


IEEE, the world’s largest technical professional organization dedicated to advancing technology for humanity, and the IEEE Standards Association (IEEE-SA), today announced the publication and availability of IEEE 1547-2018—Standard for Interconnection and Interoperability of Distributed Energy Resources (DER) with Associated Electric Power Systems Interfaces.

IEEE 1547 provides technical specifications for the interconnection and interoperability between utility electric power systems and distributed energy resources, addressing performance, operation, testing, safety considerations, and maintenance of the interconnection. The standard includes general requirements, response to abnormal conditions, power quality, islanding, and test specifications and requirements for design, production, installation evaluation, commissioning, and periodic testing.

“With the expansion of distributed energy resources, a cross-section of Industry stakeholders has come together to address numerous changes related to the rising levels of solar and other DERs on the grid, such as meeting requirements for the provision of reactive power and to ride through voltage and frequency disturbances,” said David Narang, chair, IEEE 1547 Revision Working Group. “The publication of IEEE 1547 provides utilities, DER developers, regulators, service companies, and equipment manufacturers a uniform set of consensus-based requirements for grid interconnection and grid support across any type and size of DER implementation.”

IEEE 1547 requirements for the interconnection of DER include those for synchronous machines, induction machines, or power inverters/converters typical to most installations. The criteria and requirements apply to all DER technologies interconnected to electrical power systems at primary and/or secondary distribution voltages. Installation of DER on radial primary and secondary distribution systems is the main emphasis of the standard, although installation of distributed energy resources on primary and secondary network distribution systems is also considered.

IEEE 1547 is available for purchase at the IEEE Standards Store.
