IEEE 2800-2022 — ride-through requirements
The LVRT, HVRT, FRT envelopes a grid-scale battery must meet under IEEE 2800-2022 (US), digitized breakpoint by breakpoint and checked against the clause it came from.
Part of: the grid-code ride-through chart — compare this against 63 other standards in 42 countries.
What this is, and is not. A reading aid compiled from the clause cited below — not a compliance document. The primary text governs. Every value here was read from a current primary source.
Breakpoints
Times are seconds from the start of the disturbance. Voltage is per-unit of nominal; frequency in hertz. An LVRT curve is a lower boundary (stay connected while voltage is on or above it), an HVRT curve an upper boundary, and FRT gives the band between its High and Low boundaries.
| Event | Duty | Breakpoints | Status |
|---|---|---|---|
| low-voltage ride-through (LVRT) | ride-through | 0.001s → 0 pu; 0.32s → 0 pu; 0.321s → 0.25 pu; 1.2s → 0.25 pu; 1.201s → 0.5 pu; 3s → 0.5 pu; 3.001s → 0.7 pu; 6s → 0.7 pu; 6.001s → 0.9 pu | verified |
| high-voltage ride-through (HVRT) | ride-through | 0.001s → 1.2 pu; 1s → 1.2 pu; 1.001s → 1.1 pu | verified |
| frequency ride-through (FRT) | ride-through | High: 0.1s → 61.8 Hz; 299s → 61.8 Hz; 299.001s → 61.2 Hz | Low: 0.1s → 57 Hz; 299s → 57 Hz; 299.001s → 58.8 Hz | verified |
Where these values come from
- LVRT IEEE 2800-2022 Clause 7.2.2.1 voltage ride-through table for 'plants without aux. load limitations' (solar/BESS), reproduced with IEEE copyright permission on slide 44 of the official IEEE PES / IEEE 2800 WG + SEIA/ACP joint webinar (31 May 2022): V>1.20 may trip; V>1.10 mandatory 1.0 s; V>1.05 continuous 1800 s; V<0.90 mandatory 6.00 s; V<0.70 3.00 s; V<0.50 1.20 s; V<0.25 0.32 s; V<0.10 permissive 0.32 s — with the step-curve plotted at 0.32/1.2/3.0/6.0 s. (slide 44; slide 43 is the wind table with 3.00/2.50/1.20/0.16/0.16). Independently corroborated by NERC PRC-029-1 Attachment 1 Table 2 ('All Other IBR' incl. PV+BESS: 6.00/3.00/1.20/0.32/0.32) and by the ERCOT NOGRR245 Voltage Ride-Through Capability Table ('Preferred Requirements … PVGR or ESR': 0.7 pu→6.0 s, 0.5→3.0, 0.25→1.2, 0→0.32).
- HVRT IEEE 2800-2022 Clause 7.2.2.1 table (IEEE-copyright reprint, IEEE PES/2800 WG webinar slide 44): 'V > 1.20 — may ride-through or may trip — NA; V > 1.10 — Mandatory operation — 1.0 s; V > 1.05 — Continuous operation — 1800 s'. Matches NERC PRC-029-1 Attachment 1 Table 2 ('>1.10 Mandatory Operation 1.0 s; >1.05 Continuous 1800 s') and ERCOT NOGRR245 ('1.2 pu → 1 s' preferred requirement).
- FRT IEEE 2800-2022 Clause 7.3.2.1 frequency ride-through table (IEEE-copyright reprint, IEEE PES/2800 WG + SEIA/ACP webinar slide 35): 'f1,f4 | +3, −5 | 299.0 (t1) | Mandatory operation' and 'f2,f3 | +2, −2 | ∞ | Continuous operation'. Corroborated by NERC PRC-029-1 Attachment 2 Table 3: >61.8 may trip; >61.2 → 299 s; 58.8–61.2 continuous; <58.8 → 299 s; <57.0 may trip.
