IEEE 1547 - Distribution Interconnection Coordination

This page provides information related to MISO's coordination with distribution interconnection standard IEEE 1547-2018.


IEEE Std 1547-2018 (abbreviated IEEE 1547) is a newly published standard for distributed energy resources (DERs) interconnection and interoperability requirements.  It is a technology-neutral, voluntary IEEE standard that has been highly vetted by a large group of stakeholders with the aim to harmonize technical interconnection performance capability requirements and functional specifications  for the growing installations of distributed generation and energy storage systems IEEE,

In 2018, IEEE 1547 added new requirements regarding voltage and frequency ride-through capability, to help the reliability of the Transmission system.  It includes provisions for coordination with Reliability Coordinators, which is MISO in the MISO region.  MISO would like to coordinate with the distribution utilities and experts to provide a regional preferred choice of performance category and setting selection.
