In Constant/Flat Interchange Control mode, the Automatic Generation Control (AGC) specifically responds to interchange deviations. This mode focuses on maintaining the scheduled interchange between different balancing authorities at the level that has been predetermined.

Interchange deviations occur when the actual flows of electricity between areas deviate from the scheduled amounts, which can happen due to generation or load changes. The goal in this mode is to ensure that the interchange between resources remains balanced according to the schedules agreed upon by the participating utilities.

While frequency is a crucial aspect of overall grid stability, in this specific control mode, AGC's primary function is to correct for interchange discrepancies rather than to focus on frequency regulation. Therefore, choosing to focus on interchange deviations aligns directly with the core function of Constant/Flat Interchange Control mode.
