Abstract: This paper presents a decentralized Model Predictive Control (MPC) design for the Load Frequency Control (LFC) problem. The Area Control Error (ACE) signal was used as the only input to the controller to achieve the decentralized scheme. A part of the ACE signal, which reffers to changes in interarea tieline power flow, and local changes in power demand are treated as an unmeasured disturbance for the controller design. Simulation is performed on a three-area power system model with three different load disturbance scenarios. The results are presented and compared to those obtained using PI controllers.
