Mppt based multilevel inverter controlled grid connected wind power system

Wind turbine generator module is the widely used system. Small wind generated powers are cascaded and connected to the grid with a constant AC supply. Wind turbine which gets subjected to various speeds of wind cannot supply a constant DC voltage. A traditional method to avoid this problem is to control either of active or reactive power to control this voltage. This paper concentrates on the control of both active and reactive powers using DC-DC Converters with MPPT technique to keep the output DC voltage without fluctuations. PI controller is used to apply this MPPT technique. A comparative study of the traditional method with the proposed system has been made with the help of MATLAB Simulink software.
