Enhanced one-step-ahead adaptive control technique for wind systems

Abstract

This article proposes an enhanced version of the one-step-ahead control algorithm applied to a wind system. The wind system is considered as an isolate source of power and it is composed of a horizontal-axis wind turbine connected to an induction generator: consistent mathematical models for the horizontal-axis wind turbine and the induction generator will be introduced. Although the main strength of the one-step-ahead control technique is its adaptivity, nevertheless its convergence rate reduces very quickly. This aspect shows the primary algorithm weakness and is the reason for the proposed enhancement. Finally, the results of control problems will prove the reliability of the suggested enhanced control technique.
