    Abstract: The investigation of the distribution of wind power and its prediction error probability is necessary. It has a significant meaning to the analysis of wind power distribution characteristics. In this paper, the average value of wind power and daily power fluctuations were used as indicators to statistically analyze the probability distribution of wind power fluctuations on different time scales. The normal distribution model has problems of poor-fitting effect on wind power and prediction error distribution. This study used a non-parametric estimation method to fit wind power and its short-term prediction error probability distribution. It also used the residual sum of squares and correlation coefficient as evaluation indicators to compare the fitting effects of different prediction models and sampling intervals. The analysis result based on the measured data shows that the non-parametric estimation method can effectively fit the probability distribution of wind power and its short-term forecast error, and it has well practicability.
    Key words: wind power; probability distribution; short-term forecast; forecast error distribution; non-parametric estimation
