摘　　要：通过福建省某沿海风电场的出力数据,验证了风电出力变化的波动性及随机特性,将风电出力并入电力负荷,分析了风电并入后对于电力负荷变化特性的影响,并分别从电网与风电自身的角度出发,讨论了有效应对风电功率的不确定性措施,包括风电出力预测、储能手段以及风电机组自参与调频等。This paper, first of all, validates and analyzes the fluctuations and stochastic characteristics of wind power output based on the data from a certain wind farm in the coastal area in Fujian, and then explores the effects of wind power integration on the power load characteristics, and discusses possible measures for effectively responding to the wind power uncertainty from point of view of both power grid and wind power itself. These measures include accurate wind power forecasting and suitable energy-storage and self-adjustment of frequency by the wind power generator.
