<br/><br/> Self-excited induction generators usually suffer from variable output voltage frequency  and magnitude with variation of wind speed when they are used in stand-alone variable  speed Wind Energy Conversion Systems (VSWECS). The doubly-fed induction  generators (DFIGs) have been used in stand-alone VSWECS applications. Controlling  the magnitude and frequency of the stator output voltage for DFIG achieved by  controlling the rotor input voltage, magnitude and frequency. The maximum power  point tracking control technique is applied to DFIG for optimum operating point
