Analysis on Fluctuation Characteristics of Wind Power

Abstract

Fluctuation is an inherent property of wind power. Analyzing fluctuation of wind power has a significant meaning either for improving prediction accuracy of wind power or for overcoming disadvantages coming from wind power and power grid connection. Based on methods of statistics analysis and fitting, starting with a wind power plant, this paper analyzed the characteristics of probability distribution of wind power fluctuation. We selected wind power data from different sites and time scales, based on variation of probability distribution characteristics, this paper researched fluctuation of wind power under different spatial and time scales.This paper pointed out power fluctuation difference between single wind machine and the whole wind power plant.
