摘要：For the problem of uncertain external disturbances which are always present in modern power systems, 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 this paper, the dynamic model of multi-area interconnected power system is introduced, and the DMPC is proposed to replace the traditional PI control. For the constraint of generator power rate of change, the control system uses the dynamic equation of state of the interconnected power system as the DMPC prediction model. The disturbance is the change of the load and the input change of the governor. The predicted output is the area control error (ACE). The power system consists of subsystems that contain their own controllers, and the controllers in each region integrate the information of the other controllers into the control targets to facilitate coordination. The DMPC algorithm proposed in this paper ensures the applicability and stability of the DMPC algorithm in the LFC system and reduces the communication requirements at the same time. Simulation results show that closed loop performance and robustness are greatly improved compared with the traditional methods.
