B. Secondary Control

[UCTE Operation Handbook Appendix 1 Chapter A: Secondary Control, 2004]
[UCPTE Rule 44: Control of active power in the grid of the UCPTE, 1990]
[UCPTE-Ground Rules concerning primary and secondary control of frequency and active power within
the UCPTE, 1998]

Introduction
SECONDARY CONTROL maintains a balance between GENERATION and consumption (DEMAND)
within each CONTROL AREA / BLOCK as well as the SYSTEM FREQUENCY within the
SYNCHRONOUS AREA, taking into account the CONTROL PROGRAM, without impairing the
PRIMARY CONTROL that is operated in the SYNCHRONOUS AREA in parallel but by a margin of
seconds (see !P1-A).

SECONDARY CONTROL makes use of a centralised AUTOMATIC GENERATION CONTROL,
modifying the active power set points / adjustments of GENERATION SETS in the time-frame of
seconds to typically 15 minutes. SECONDARY CONTROL is based on SECONDARY CONTROL
RESERVES that is under automatic control. Adequate SECONDARY CONTROL depends on
generation resources made available by generation companies to the TSOs. Please refer to
Appendix 1 (see !A1-B) for basics and principles of SECONDARY CONTROL.

This policy section replaces the corresponding sections for secondary control in the latest
“UCPTE-Ground Rules concerning primary and secondary control of frequency and active
power within the UCPTE”, dated 1998.

Secondary frequency control, also known as Load Frequency Control (LFC), employs a central controller called the Automatic Generation Control (AGC). The AGC reacts slower than primary control but has an integral part in the control loop. It is thus able to bring the system frequency back to nominal frequency, depending on the grid region 50 Hz or 60 Hz, as well as to keep exchanges between areas at the scheduled value. While secondary control could also handle lasting generation-demand mismatches, it is desirable to relieve this service to prepare for future disturbances.
