Turkey (TEİAŞ Şebeke Yönetmeliği Ek-18) — ride-through requirements

The LVRT, FRT envelopes a grid-scale battery must meet under Turkey (TEİAŞ Şebeke Yönetmeliği Ek-18), 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. 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.

Where these values come from

  • LVRTElektrik Şebeke Yönetmeliği (EPDK/TEİAŞ), EK-18 §E.18.2 'ÜRETİM TESİSLERİNİN ARIZA SONRASI SİSTEME KATKISI' + Şekil E.18.1, as introduced by the amendment of 22.04.2017 (Resmî Gazete 30046) — verified in the official annex PDF resmigazete.gov.tr/eskiler/2017/04/20170422-8-1.pdf, p. 1. The code defines a linear recovery ramp; the vertices are read from the clause and the chart draws the segment between them.
  • FRTElektrik Şebeke Yönetmeliği, EK-18 §E.18.4 'FREKANS TEPKİSİ' as replaced by MADDE 10 of the amending regulation of 21.01.2025 (Resmî Gazete 32789), Tablo E.18.1 'Rüzgar ve güneş enerjisine dayalı fotovoltaik üretim tesisleri için frekans aralıklarındaki çalışma süreleri'.

Any event not in the table above is not plotted for this code. Where an absence is itself the finding — a code that defines no high-voltage envelope, or one whose curves circulate under another country's name — it is recorded in the grid codes with no ride-through curve.
