When there is a power generation imbalance and consumption among two areas connected by a tie-line, the power flow on the tie-line changes, which can impact the frequency stability. To avoid this, tie-line power frequency stability control is implemented to ensure that the frequency remains stable and within acceptable limits.

For multi-area interconnected power system network, LFC is introduced considering area interchange control (AIC) concept. Integral (I), Integral derivative (ID) and proportional integral derivative (PID), controllers are used to mitigate the frequency oscillations as well as tie-line power deviation between different areas.
The load in each area is represented as a constant power load, i.e., the power consumed is constant irrespective of the frequency. The tie-line between the two areas is represented as a transmission line with a resistance and reactance.
