Abstract

In this paper, a new robust control scheme for decentralized generator excitation control systems to improve power system stability is proposed. By using generator terminal voltage magnitude and phase angle to represent the interactions among generators, decentralized generator excitation control in multi-machine power systems can be achieved. The control is realized by applying a disturbance rejection control based on robust control design approach. Simulation results show that the proposed robust excitation control improves overall power system stability
