A functional model predictive control approach for power system load frequency control considering generation rate constraint

摘要

In this paper, a wide area measurement, centralized, load frequency control using model predictive controln(MPC) is presented for multi-area power systems. A multivariable constrained MPC was used to calculatenoptimal control actions including generation rate constraints. To alleviate computational effort and to reducennumerical problems, particularly in large prediction horizon, an exponentially weighted functional MPCnwas employed. Time-based simulation studies were performed on a three-area power system, and the resultsnwere then compared with decentralized MPC and classical PI controller. The results show that the proposednMPC scheme offers significantly better performance against load disturbance. Copyright © 2011 JohnnWiley & Sons, Ltd.
