The wind farm is a collection of all wind turbine generators situated at a particular distance. The wind speed and wind direction play an important role in wind farm power calculation. The power curve of the wind farm is not simply the summation of the wind turbine’s power curve. It is complex due to the intermittent nature of wind speed and its direction. The power curve is obtained from the data taking the wind speed and wind power at that speed. There are many logistic functions used in the literature to analyze the wind power curve that helps to calculate wind farm power output and energy generated. In this paper, the 3-parameter deterministic process (3P-DP) method is used for wind power curve calculation. The wake effect is analyzed by Jensen’s model with wind speed and wind direction. The wind farm power is obtained from the new proposed formula and compared with the already existing one. The results are verified from real data obtained from the literature.
