Abstract

Due to the various advantages of Brushless Cascaded Doubly Fed Induction Generators (BCDFIG), they are an attractive solution to be employed in grid-connected wind energy systems. In this paper, a novel direct power control strategy based on backstepping algorithm, is proposed for BCDFIG. The most well-known traditional control method for BCDFIG is the vector control strategy, which has several disadvantages such as dependence on the operating point, the need for accurately adjusting the parameters of multiple PI controllers, etc. The operating principles of the proposed method are based on controlling the references of active and reactive powers, by using the backstepping algorithm and defining appropriate Lyapunov function. The proposed controller overvomes the aforementioned drawbacks of the vector control method and improves its performance in different operating conditions. Finally, the proposed and vector control schemes for BCDFIG have been implemented in the MATLAB/Simulink software and their performances are compared.
