摘　　要：为减少大型并网风电场输出功率不稳定给系统频率造成的较大影响,在Matlab平台中仿真了风电机组输出功率随风速变化的规律,以风电机组输出功率特性函数和风电场风速概率分布函数为基础,提出了一种计算大型风电系统长时间稳定输出所需储能容量的方法,并用实际风电场数据验证了该方法的有效性,以期为风电场设计提供决策参考。To mitigate the great impact of instable power output of grid-connected large-scale wind farm on system frequency, the rule, by which the power output of wind power generation unit varies with wind speed, is simulated by Matlab. Based on characteristic function of wind power generation unit＇s output power and the probability distribution function of wind speed in wind farm, a method to calculate the required energy-storage capacity for long-term stable power output of large-scale wind farm is proposed. The proposed method is verified by the data from actual wind farm.
