Abstract：Wind power is a kind of power with stochastic volatility output power. Different sampling time lengths may affect the preciseness of analysis results when analyzing the characteristic of wind power fluctuation. We expect to find one sampling time length which can make the analysis result closest to the fundamental volatile features and shorten the computation and analysis time in project, and named this sampling time length as the intrinsic time scale. Firstly, this paper establishes the index system that is able to depict the volatile features of wind power, and then analyzes the change rules and trends of all indexes under different time scales. Finally, this paper discusses the impact of sampling time on the wind power characteristics in detail and determines the intrinsic time scale.
