Nonlinear decentralized control of a multimachine power system
In this paper, the transient stability and voltage regulation of multimachine power systems are simultaneously addressed in a multivariable and nonlinear framework. The design method is based on a new power system model. The main characteristic of this model is that interactions between generators and changes in operating conditions are represented by time-varying parameters. The controller consists of two controllers, known as the terminal voltage controller and speed controller. The methodology adopted is based on backstepping design strategy. The proposed stabilizing feedback laws for the power system are shown to be globally asymptotically stable in the context of Lyapunov theory. The tracking errors are shown to be globally uniformly bounded. Numerical results are presented to demonstrate the effectiveness of the proposed control methodology.
