Preface

Doubly fed induction generators and permanent magnet synchronous generators are the two main types of variable speed wind generators. Changes brought about by the grid connection of variable speed wind generators in an AC power system are twofold. Firstly, unlike conventional synchronous generators, which are linked directly to the power system, a variable speed wind generator is connected to the grid via controlled voltage source converters. The dynamic behavior of the variable speed wind generator is significantly different from that of a synchronous generator. The impact of dynamic interactions introduced by the grid-connected variable speed wind generator on power system stability needs to be examined carefully. In addition, wind generation is variable due to the stochastic fluctuation
