Sliding Mode MPPT Control of a Dual Stator Induction Generator for Wind Power Generation

This paper proposes a robust sliding mode controller based on an indirect vector control of Dual stator Induction Generator (DSIG) for a variable speed wind integrated into the network. The main goal of this paper is to improve and to optimize the performances of power system using a wind energy conversion system based on DSIG. In first step, The modeling of variable-speed wind energy conversion system is presented. In second step, a field-oriented control of a DSIG is proposed. In the last step, in order to ensure an optimum operating point and a Maximum Power Point Track (MPPT) giving online a maximum production of electric power for different wind speeds, a sliding mode controller have been suggested . The efficiency and validity of the proposed control strategy are illustrated by simulation results.
