By development of the power system in presence of the sustainable energies, the issue of grid frequency control is becoming more important. In traditional power systems, the frequency is mostly controlled by the hydroelectric power plants. This makes it troublesome in cases of dry spell or the absence of the hydro power plants. In this paper, a new method based on using wind farm equipped with PMSG, connected through HVDC link and controlled by fuzzy logic controller, is proposed to investigate the feasibility of using wind farms to improve the frequency control performance. The proposed system is tested on a four area grid and simulated in MATLAB /Simulink. It is concluded that the best performance, which is up to 26% improvement in settling time of the frequency deviation, is achieved by the proposed system in comparison to using the traditional control method and using wind farm controlled by conventional controllers.
