A Study on Wind Farm Modeling Method with the Stochastic Volatility of Wind Velocity and Wind Direction Considered

This paper proposes a modeling method for wind farms from the angle of the predictability of the stochastic wind velocity and direction, and then establishes the wind farm stochastic model. The operation characteristics of the wind farm is simulated to serve the goal of predictability and controllability of large-scaled wind power, Additionally, the rationality of this modeling method is validated via the comparison between the equivalent model and the detailed model of the wind farm. Finally the paper concludes that the influence of the stochastic volatility of wind velocity and direction should be taken into consideration when the model is established to study the dynamic behavior of wind power and its influence on power system.
