In the large scale applications, sometimes it is essential that the control theories be distributed or decentralized. In this paper, regarding large scale of power systems and advantages of model predictive control (MPC), a constraint predictive control method that is called “Receding Horizon Control (RHC)”, used for load frequency control in a two-area power system with two cooperating methods of agents. The main advantage of decentralized control is complexity reduction in computations. Moreover, in the application of centralized control, online computation of inputs (high dimensions) is complex, and non-flexible, and impractical. Finally using of simulations, centralized and decentralized control methods, cooperative methods are compared under a variety of disturbances.
