Abstract-In this paper, a systematic method of choosing the gain parameter of the wind turbine generator
pitch control is presented, using the Lyapunov technique, that guarantees stability. prehensive
puter model of a hybrid wind-Diesel power generation system, including the Diesel and wind
power dynamics with a superconducting ic energy storage (SMES) unit, for stability evaluation
is developed. The effect of introducing the SMES unit for improvement of stability and system dynamic
response is studied. Analysis of the stability has been further explored using an eigenvalue sensitivity
technique. The eigenvalues of the system with and without the SMES unit have been studied, and the
effects of variation of the SMES unit parameters or eigenvalue locations are plotted. The dynamic response
of the power system to random load changes with optimal gain setting is also presented. 0 1997 Elsevier

INTRODUCTION
In many remote and munities, electricity is mainly supplied by small Diesel-based
power systems. The high cost of fuel for these small systems is mainly due to the long distance
delivery of relatively small fuel quantities. An urgent need to introduce alternative energy sources
into these remote areas and reduce their dependence on fuel has attracted many researchers. Wind
turbine generators are the most advanced among the alternative energy technologies and are
expected to find their economically viable applications in these a
