Abstract 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 |
