IEEE 1547.2-2023

IEEE 1547.2-2023 is a practical application guide for IEEE Std 1547-2018, focused on the interconnection and interoperability of distributed energy resources with associated electric power systems interfaces. It helps engineers and planners understand how the core standard may be applied in field and system contexts, where power, energy, and electromagnetic considerations intersect. For organizations working on DER integration, it supports more consistent technical interpretation and implementation.

Overview of IEEE 1547.2-2023

This technical document supplements IEEE 1547 by providing guidance rather than replacing the underlying interconnection standard. IEEE 1547.2-2023 is intended to help users interpret requirements, coordinate interfaces, and apply the standard across distributed generation and related electric power systems. Its guidance is especially relevant when aligning system behavior, interoperability expectations, and engineering practices in projects that involve utility-connected distributed energy resources and associated control or communication interfaces.

Typical use cases

This guide is commonly used when planning or reviewing DER interconnection studies, utility interface specifications, and project documentation for inverter-based resources, energy storage, and other distributed generation equipment. It may also support testing and acceptance workflows where engineers need a clearer path from IEEE 1547 requirements to practical deployment. In power system environments, it is useful for teams responsible for site design, interface coordination, and operational consistency across connected equipment.

Why it matters

Clear application guidance can reduce ambiguity during procurement, design review, and compliance verification. IEEE 1547.2-2023 matters because interconnection projects often depend on consistent interpretation of technical requirements at the equipment and system interface level. Using a guide like this may help reduce integration risk, improve documentation quality, and support more predictable performance when distributed energy resources are connected to electric power systems. It is a useful reference for stakeholders who need aligned engineering decisions.
