Optimized Control for PMSG Wind Turbine Systems under Unbalanced and Distorted Grid Voltage Scenarios

Wind energy is one of the fastest growing energies due to its feasible cost and environment friendly nature, where there no emission waste or greenhouse gases emission. systems should be connected electric utility avoid effects intermittent nature these sources. One main problems integration wind turbines unbalanced voltage grid. Many efforts have been made remedy grid with utility. This research points out need for more accurate robust controllers, such as those mentioned in this paper. A novel combination strategy presented paper overcome inherent imbalance voltages when used a permanent magnet synchronous generator (PMSG). technique designed adapt positive sequence dq-axis output current from PMSG extract maximum power available turbine. Meanwhile, negative component improve quality controller introduced side converter compensate 2nd 6th components currents. Using controllers reduces all dominant currents permits tracker available. detailed simulation experimental studies are show operation under different operating conditions. The results proposed superiority fully remedying effect voltages.
