In order to meet increasing power demand, taking into account economical and environmental factors, wind energy conversion is gradually gaining interest as a suitable source of renewable energy. The permanent magnet Synchronous generator can offer high efficiency and power density and these advantages make it very attractive for wind power applications for variable speed operation. In the variable-speed wind energy conversion system (WECS) the wind turbine can be operated as close as possible to its optimal speed to realize maximum power point tracking for various wind speeds. To take the advantage of higher energy capture power electronics interfaces must be provided between machine and grid terminals. The back-to-back PWM converter-based power electronic interface is suitable option for the permanent magnet generator in wind power applications. In WECS the turbulence of the wind will result in power variations which will affect the DC link voltage and the power quality in the grid. In this paper a fuzzy logic controller is designed for reducing the DC link voltage ripples of the permanent magnet wind power generation system. The modeling of WECS is developed in MATLAB- SIMULINK. The correctness and effectiveness of the proposed fuzzy logic controller are verified by the simulation results.
