Comparative study of power converter topologies and control strategies for the harmonic performance of variable-speed wind turbine generator systems
TL;DR: In this paper, a fractional-order control strategy is proposed for variable-speed operation of wind turbine generator systems. And the results reveal that the multilevel converter and the proposed fractional order control strategy enable an improvement in the power quality, in comparison with the other power converters using a classical integer-order controlling strategy.
