Wind mill energy conversion system (Matlab Project)

      This paper presents a full detailed modeling and a new  control scheme of a three-phase grid-connected wind energy conversion system (WECS).  The WECS model consists of a variable speed wind turbine generator and the electronic power conditioning  system is composed of a back-to-back AC-DC-AC power converter. The control consists of a multi-level hierarchical structure and incorporates a maximum power point tracker (MPPT) for best use of the wind  resource. In addition, reactive power compensation of the electric grid is included, operating simultaneously  and independently of the active power generation. A three-level voltage source inverter (VSI) is used as  interface with the AC power grid. Validation of models and control schemes is performed by using the  MATLAB/Simulink environment. Moreover, a 400 W WECS experimental set-up was employed to demonstrate the accuracy of proposed models and control algorithms
