Nonlinear Backstepping with Integral Action for Wind Power Plant Based on Doubly Fed Induction Generator Connected to the Non-Ideal Grid

Nonlinear Backstepping with Integral Action for Wind Power Plant Based on Doubly Fed Induction... This paper suggests the integral Backstepping nonlinear control of the wind power plant based on the Doubly-Fed Induction Generator connected to the grid in normal conditions and under parameters variation. The stator of the generator is explicitly linked with the electrical network. However, the rotor winding is associated with the grid via a bidirectional AC/DC/AC converter. The purpose of this paper is to control the powers produced by a variable speed wind turbine, pilot the exchanged power between the system and the electrical grid and regulate the voltage of the continuous bus capacitor.

Abstract

This paper suggests the integral Backstepping nonlinear control of the wind power plant based on the Doubly-Fed Induction Generator connected to the grid in normal conditions and under parameters variation. The stator of the generator is explicitly linked with the electrical network. However, the rotor winding is associated with the grid via a bidirectional AC/DC/AC converter. The purpose of this paper is to control the powers produced by a variable speed wind turbine, pilot the exchanged power between the system and the electrical grid and regulate the voltage of the continuous bus capacitor. Besides, the suggested method is applied to establish the maximum power tracking strategy. The Backstepping control law is established founded on the stability of the Lyapunov function. The proposed control is performed and compared with the conventional Backstepping and the indirect field-aligned control. Discussion of the principle and elaboration of the Integral Backstepping laws are achieved. Performance tests are realized by MATLAB/ Simulink software. From the simulation results, the effectiveness and superiority of the Integral Backstepping are well demonstrated.
