Cascaded PI Controller based Wind Turbine Generator System for Battery Charging Applications

Wind turbine generator system is a promising alternative to fossil fuel based sources of energy. In recent decades, this technology has seen rapid developments with respect to efficiency and versatility. This paper proposes a wind turbine-permanent magnet synchronous generator-buck converter system for battery charging applications using MATLAB/Simulink Cascaded proportional integral (PI) control was used to provide gate signals to the mosfet. Various permutations and combinations have been considered in input wind speed and the battery's initial state of charge. It is observed that the dynamic response of the system is robust and time to attain steady state stability is desirously less.
