Abstract

A new decentralized nonlinear voltage controller for multimachine power systems is proposed in this paper. The nonlinear n-machine power system model is first linearized and decoupled over the whole operating region by using the direct feedback linearization (DFL) technique. Then a decentralized nonlinear voltage controller is developed by use of the robust control theory. Performance of the proposed controller in a three-machine example system is simulated. The simulation results show that both voltage regulation and system stability enhancement can be achieved with this proposed controller regardless of the system operating conditions
