scope:

This standard establishes criteria and requirements for interconnection of distributed energy resources with electric power systems (EPSs) and associated interfaces. The stated technical specifications and requirements are universally needed for interconnection and interoperability of distributed energy resources (DERs)² and will be sufficient for most installations.³ The specified performance requirements apply at the time of interconnection and as long as the DER remains in service.

Purpose

This document provides a uniform standard for the interconnection and interoperability of distributed energy resources with electric power systems. It provides requirements relevant to the interconnection and interoperability performance, operation and testing, and, to safety, maintenance and security considerations.

²For example, synchronous machines, induction machines, or static power inverters/converters.

³Additional technical requirements may be necessary for higher DER penetration situations.
