Abstarct: The need of human being to the electricity in recent century, limitation on fossil fuels sources and increment of environmental considerations cause increment in using of renewable resources in recent decades. These sources of energy had a little penetration in energy generation whether neglected in load frequency model or they were modeled incompletely or they were considered as negative loads. But, according to the increase of renewable energy sources using, it is necessary to pay attention to these sources dynamic partnership that was neglected before. The goal of this thesis is using of wind farms as dispatchable power sources for partnership in network frequency control. To this aim, the model of wind farm has been derived at first, and baxsed on this model the proper control method has proposed. Then several scenarios for wind farms partnership in load frequency control have been evaluated. The results of simulations show the effectiveness of the proposed control method for frequency regulation of network.
