Colombia (CREG 060/2019) — ride-through requirements

The LVRT, HVRT envelopes a grid-scale battery must meet under Colombia (CREG 060/2019), digitized breakpoint by breakpoint and checked against the clause it came from.

Applies to: transmission connections — Wind + PV plants on the STN/STR, 500 kV excluded.

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.

Where these values come from

  • LVRTResolución CREG 060 de 2019, Artículo 14 (modifica numeral 5.7 lit. c) del Código de Operación), figura 'Característica de LVRT y HVRT para plantas eólicas y solares fotovoltaicas con conexión a STN y STR (no incluye 500 kV)' — verified from the official embedded graphic resolucion_creg_0060_2019_obj_2.gif. The code defines a linear recovery ramp; the vertices are read from the clause and the chart draws the segment between them.

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.
