Analysis of the power coefficient for a wind generation system

This paper presents an analysis of the conditions and problems that occur when Wind Generation Systems operates in different mode of tracking maximum power. The analysis focuses on the effect of the power coefficient of the wind turbine in the condition of balance of power between the wind generation systems and the electrical network. In the specialized literature there are not enough papers that address this problem. Therefore, in the present paper this problem is solved, showing that there are two desired mechanical speeds for the one particular operating condition of the wind generation systems when this is interacting with the electrical network for each wind speed value
