Study of Volatility Probability Distribution of Multiparametic Net Wind Power Output
When wind farms output net wind power,wind speed,turbulence intensity,and wind shear and other factors lead to an increase in the volatility of grid-connected output power,which in turn increases the voltage of the distribution grid.To ensure the safe operation of the distribution network,a volatility probability distribution of multiparameter net wind power output is investigated.According to the analysis results of wind speed,turbulence intensity and wind shear coefficient which affect the wind power fluctuation,the wind turbine output power fluctuation is extracted by using the empirical modal decomposition method of complex data.Wind speed,wind shear coefficient,and turbulence intensity and other parameter are used as the constraints,and the probability distribution model of the net output power volatility of the wind power is established and calibrated to achieve the accurate acquisition of the probability distribution characteristics of the net output power fluctuation of the wind power.The experimental results show that the probability distribution error of the model is within 0.01％,with high accuracy.The fluctuation probability value of the model is like that of the fluctuation probability value of the wind farm power volatility probability distribution.The model is more effective.
