Robust control and analysis of a wind-diesel hybrid power plant

The aim of this paper is twofold: first to present multivariable frequency domain techniques as a tool for controller design and dynamic analysis of an autonomous wind-diesel power system; and secondly to study how robust model based controllers can be designed for such systems. Dynamic system analyses using multivariable frequency domain techniques are verified against detailed nonlinear simulation studies. The results are encouraging in the sense that the main conclusions in terms of robust stability and performance agree very well with the simulation results. It is also shown that improved performance of the system can be achieved using simple model based controllers.<
