Optimized active power control of DFIG wind farm

Abstract

To increase the stability and efficiency of the Grid with wind power integration, one of the solutions is to control the active power output of wind farms. This paper focuses on wind farms with DFIG wind turbines, and analyzes the stability of DFIGs working in different control strategies. An optimized control strategy is proposed that guides the active power output of a DFIG wind farm to follow the reference power curve. By controlling the rotating speed of the DFIGs in a wind farm, the control strategy minimizes the amount of energy loss during its operation. Simulation results show that the control strategy can effectively follow the reference power curve and keep the DFIGs stable.
