IEEE 1547.1/UL 1741 Introduction and Overview

Why are we including a standard that was originally a safety standard for interconnecting a power generating system (Distributed Energy Resource = DER) to an AC grid? First, it is a grid edge standard. But more importantly, IEEE 1547-2018 has evolved into both a smart inverter functional standard and it addresses the issue of communications interoperability between a grid operator and DER. Because it is both the mandated and default standard in the US for interconnection of DERs to the grid, IEEE 1547-2018 promises to have a profound impact on smart grid interoperability in coming years.
