IEEE 1547 interconnection requirements for distributed energy resources, anti-islanding protection, voltage/frequency ride-through, the utility interconnection application process, and what pushes a project from fast-track into a supplemental or full interconnection study.
Every distributed energy resource — solar PV, battery storage, wind, or a combination — has to behave in a defined way at its point of common coupling with the utility grid before it can legally export power. This module covers what IEEE 1547 actually requires: how an inverter detects and shuts down during an unintentional island, why the 2018 revision replaced automatic tripping with mandatory voltage and frequency ride-through, and how the utility interconnection application process — fast-track screening, supplemental review, or a full interconnection study — decides which path a given project takes.
By the end of this module you should be able to work through a fast-track aggregate-capacity screen the way a utility engineer actually checks it, and explain why a technically flawless DER design can still be routed into a full interconnection study for reasons that have nothing to do with the DER's own equipment.
