Abstract :
In this letter, a stand-alone power system with doubly fed induction generator is described. Direct voltage control based on the stator voltage vector, represented in rotating polar frame, does not need any feedback from the rotor speed or position. Using positive- and negative-sequence components, an unbalanced load can be supplied
