Improvement of the performances for wind energy conversions systems
Abstract
In this paper, a contribution to improvement of the performances for wind energy conversions systems (WECS) is investigated. This paper introduces, on one hand, a direct AC–AC matrix converter system as an alternative to the conventional AC–DC–AC converter configuration for the WECS and the two-quadrant operated mode of the DFIG, on the other one. The WECS considered is based to the wind turbine (aerodynamic), doubly-fed induction generator (DFIG), the AC/AC direct converter and the flywheel energy storage system (FESS). Simulation results obtained on the basis of the dynamic models of the wind generator are presented, for different operating points, to demonstrate the performance of the proposed system.
