Abstract Recently, doubly fed induction generators (DFIG) and synchronous generators have been applied mostly to wind power generation, and variable speed control and power factor control have been implemented for high efficiency of wind energy capture and for high quality of power system voltage. In variable speed control, the wind speed or generator speed is used for maximum power point tracking. However, the properties of wind generation power fluctuations due to wind speed variation have not yet been investigated for those forms of control. The authors discuss power smoothing by these forms of control for DFIG interconnected to a 6.6‐kV distribution line. The performance is verified by means of the power PSCAD/EMTDC system simulation software for actual wind speed data and is investigated by using an approximate equation for wind generation power fluctuations as a result of wind speed variation. © 2011 Wiley Periodicals, Inc.
