Morocco (CRENT) — ride-through requirements

The HVRT, FRT envelopes a grid-scale battery must meet under Morocco (CRENT) (Morocco), 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. Some values on this page are marked partial: the level is confirmed but at least one duration step could not be read directly from the 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
high-voltage ride-through (HVRT) ride-through 0.001s → 1.2 pu; 20s → 1.2 pu; 20.001s → 1.15 pu partial
frequency ride-through (FRT) ride-through High: 0.1s → 53 Hz; 10s → 53 Hz; 10.001s → 52 Hz | Low: 0.1s → 46.5 Hz; 10s → 46.5 Hz; 10.001s → 47 Hz verified

Where these values come from

  • HVRT CRENT Article 78 §5 'Tenue aux variations de la Tension', table for 225 kV / 150 kV / 60 kV connection voltages (ANRE, anre.ma/crent_chapitre/article-78/).
  • FRT Maroc, Code du Reseau Electrique National de Transport (CRENT), Article 78 §3 'Tenue aux Variations de Frequence', published by ANRE (anre.ma/crent_chapitre/article-78/); CRENT in force since 3 January 2022.
