Connecting power plants to automatic frequency control

Automatic power and frequency control holds the grid’s frequency in isolated operation and balances power flows with neighbouring systems. Faceplate connected power plants to it and built consumption forecasting with a machine-learning model for every station and substation.

The ask

Automatic power and frequency control (APFC) keeps the frequency stable when Kazakhstan’s power system runs on its own, and regulates power flows with neighbouring countries when the systems run in parallel. It is one of KEGOC’s key smart-grid projects under the Digital Kazakhstan programme.

What Faceplate built

A separate project from the national dispatch system, now completed. Together with KEGOC, Faceplate built the digital link that connects power plants to the APFC system.

Plants connect to automatic control through one platform
A machine-learning model for every station and substation feeds the next-day national consumption forecast
Forecasts let dispatchers act before a problem develops, not after

Why it matters

Renewable generation is variable. APFC compensates for it automatically, so connecting more wind and solar does not cost the grid its stability.
