This paper proposes a novel nonlinear decentralized control method for a class of multi-machine power systems. The aim is to construct a suitable decentralized feedback control law so as to guarantee that the large-scale interconnected power system is exponentially stable and robust against load fluctuations. To this end, we propose a novel design algorithm based on the backstepping, which involves five steps and actively utilizes the locally measurable part of the tie-line power to improve the performance. The effectiveness of the proposed control scheme is demonstrated through extensive simulation studies.
