ROBUST-CONTROL AND ANALYSIS OF A WIND DIESEL HYBRID POWER-PLANT

The aim of this paper is twofold. First to present multivariable frequ ency domain techniques as a tool for controller design and dynamic ana lysis of an autonomous wind-diesel power system. Secondly to study how robust model based controllers can be designed for such systems. Dyna mic system analyses using multivariable frequency domain techniques ar e verified against detailed nonlinear simulation studies. The results are encouraging in the sense that the main conclusions in terms of rob ust stability and performance agree very well with the simulation resu lts. It is also shown that improved performance of the system can be a chieved using simple model based controllers.
