IEEE 1547-2018 Compliance Checklist (Rev. 3.2)

IEEE Std 1547-2018 establishes mandatory requirements for the interconnection and interoperability of distributed energy resources (DERs) with the electric grid, superseding the 2003 and 2014 versions with enhanced focus on dynamic grid support functions—including voltage and frequency ride-through, active and reactive power control, anti-islanding, and seamless transition between grid-connected and islanded modes. The Rev. 3.2 Compliance Checklist translates these normative clauses into actionable, testable items organized by functional category (e.g., 'Voltage Regulation', 'Frequency Response', 'Protection & Safety'), each mapped to specific IEEE 1547-2018 sections (e.g., Clause 5.2.2.1 for overvoltage trip limits) and referencing applicable test standards such as UL 1741 SB and IEEE 1547.1. It incorporates clarifications from IEEE PAR 1547a (amendment addressing advanced inverter functions) and integrates cybersecurity considerations aligned with NIST SP 800-82 and IEEE 1547.2. The checklist is used iteratively during design review, factory acceptance testing (FAT), site commissioning, and periodic re-certification—ensuring not only static conformance but also validated real-time behavior under simulated grid disturbances (e.g., LVRT sequences per IEEE 1547.1 Annex D). Its revision history reflects evolving utility interconnection practices, including harmonization with North American Electric Reliability Corporation (NERC) standards and state-level DER integration policies like California’s Rule 21.
