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.

By Sergey Syrvachev — Director of Product Engineering at HyperStrong

Applies to: transmission connections — IBR plants at the transmission point of interconnection. Values read from an authorised reproduction of a paywalled standard.

Part of: the grid-code ride-through chart — compare this against 65 other standards in 44 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. These are the boundaries, not the behaviour: what holding one demands of the converter — reactive current injection, thermal stress, protection timing — is stepped through in the LVRT / HVRT ride-through visual.

  • LVRTIEEE 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).
  • HVRTIEEE 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).

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.
