Description: In recent years, wind energy conversion systems have been deployed in large numbers in electricity grids throughout the world. Their impact on the operation of power systems is a growing area of research. This thesis presents a control methodology for wind turbine systems that are interfaced to the grid through power-electronic converters. It is shown that fast power fluctuations excited in the conversion system by the wind can be contained rather than transferred to the grid. Also, the use of the turbine hub's energy storage capacity for filtering slow power fluctuations is explored. It is shown that a stability limit exists on the minimum filtering cut-off frequency, and that this limit can be conservatively estimated. Application of the control methodology results in a simplified model of the wind energy conversion system as a first-order filter of the incoming wind power.
