Modeling and control of grid connected wind energy conversion system with power factor correction

This article discusses the use of a Permanent Magnet Synchronous Generator (PMSG) for wind energy production and injection of the electrical energy produced in a network. The objective is to perform modeling and nonlinear control system, and then the objective of the control is: enforcing power factor correction (PFC) with respect to the power grid. First, model mathematics of the whole system studying is developed in the Park´s coordinates. Thereafter control strategies PFC is used to inject power into a grid while keeping a very good power factor. The control strategy is mainly based on the backstepping technique. A formal analysis based on Lyapunov stability is developed to describe the control system performances. To demonstrate the performance of methods, some results of the overall system simulations are presented under MATLAB / Simulink software.
