Abstract
This paper presents a load frequency control (LFC) design using the distributed model predictive control (DMPC) technique for the multi-area interconnected power system. The dynamics model of multi-area interconnected power system is introduced, and Generation Rate Constraint (GRC) and load reference setpoint constraint are considered. The overall system is decomposed into several subsystems and each has its own local area MPC controller. These subsystem-based MPCs exchange their measurements and predictions by communication and incorporate the information from other controllers into their local control objective so as to coordinate with each other. Analysis and simulation results for a three-area interconnected power system show possible improvements on closed-loop performance, computational burden and robustness, while respecting physical hard constraints.
