IEEE 1547-2018 / 1547.1-2020
IEEE 1547.1 Grid-Tied Inverter Conformance
Four-quadrant regenerative grid simulator covering 0–1.2 pu, 56–66 Hz, with programmable ROCOF to ≥3 Hz/s, phase-jump capability and sub-cycle event timing.
This standard turns on
- grid emulation
- ride-through envelopes
- anti-islanding
- ROCOF
And says nothing about
- 400 Hz
- semiconductor reliability
- automotive voltage classes
