Adaptive decentralized load frequency control of multi-area power systems

This paper addresses the load frequency control problem of multi-area power systems. A decentralized adaptive control scheme is designed; the control scheme guarantees that the fluctuations of the load frequency converge to a range, which can be made very small. Simulation results for a three-area power system are given to illustrate the developed theoretical results. The simulation results indicate that the proposed control scheme works well and it is robust to changes in the parameters of the power systems and to bounded disturbances acting on the systems.
