Research on control strategy of permanent magnet direct drive Wind Power Generation System

This paper studied strong coupling and virtual inertia problems of permanent magnet wind power systems. First, through adopted backstepping control to solve the strong coupling system and improve the dynamic performance. The grid side adopts virtual synchronous generator (VSG) control the storage system of wind power generation systems. Through the parallel output mode of wind farm system, fully play to the wind turbine short-term power support. Finally, under the different wind speeds and load conditions to verify the correctness of the researched control strategy.
