This study proposes a distributed model predictive control (DMPC) scheme for the load frequency control (LFC) problem of the multi-area interconnected power system in the presence of wind turbines (WTs). The distributed model predictive controller is designed by formulating the LFC problem as disturbance attenuation problem in the presence of both external disturbances and constraints which represent load reference setpoint, generation rate constraint (GRC) and control input constraints of the WT, respectively. The frequency response model of three-area power system concerning the aggregated WT model is introduced, in which the WT model is integrated into the interconnected power system to participate in LFC as a part of the power system. Simulation and analysis results for the three-area interconnected power system with WTs indicate possible system performance improvements, while satisfying the physical hard constraints.
