Maximum Power Point Tracking of a Variable Speed Permanent Magnet Synchronous Generator Based Wind Energy Conversion System
Abstract: Wind turbines produce maximum power at the optimal tip-speed ratio. Fixed speed wind turbines are inefficient because the turbine blades rotate at a specific mechanical speed irrespective of the prevailing wind speed. The system is therefore, not able to extract the maximum possible amount of power. In this work, a maximum power point tracking scheme for a variable-speed permanent magnet synchronous generator based wind energy conversion system is implemented in …
