چکیده :
As variable renewable generation becomes more prevalent, the challenge of maintaining real-time control over system frequency and tie-line flows intensifies. This paper proposes an automatic generation control (AGC) scheme based on model predictive control (MPC) that explicitly incorporates tie-line bias control and two distinct time scales for slow conventional generators and fast inverter-based resources. The MPC objective function penalizes Area Control Error (ACE) and tie-line deviations, with hard constraints on frequency, tie-line loading, unit outputs, and ramp rates. Simulation results on a two-area system demonstrate that under realistic disturbances, the proposed AGC significantly outperforms conventional PID-based AGC. It achieves lower mean and peak frequency deviations and maintains tie-line power closer to its scheduled value. The results suggest that the proposed MPC-based two-rate AGC framework could effectively address the critical challenges of frequency and tie-line control in the evolving low-inertia power grid.
