考虑风电机组影响的发电容量充裕度评估

Generation Capacity Adequacy Evaluation Considering the Influence of the Wind Turbine Generator

风力发电在全球范围内规模不断扩大,风机能够且正在广泛参与现代能源体系的发电行为。针对风能的间歇性等特点,建立了风速的自回归滑动平均(ARMA)时间序列模型,合理模拟实际风速。通过研究风电机组停运概率分布,使用比例分配方法创建含多状态的风电系统模型。最后,以小型RBTS测试系统为例,定量分析当风电机组接入发电系统后,发电容量充裕度指标受到的影响。

With the development and expansion of wind power in the world, wind turbines are widely in- volved in the generation of modern power systems. According to intermittence of wind energy, we establish the autoregressive moving average （ARMA） time series model of wind speed,in order to reasonably simu- late the actual wind speed. Based on the study of the probability distribution of wind turbines,we create a wind turbine model with multiple states by using the proportional distribution method. Finally, taking the small RBTS test system as an example,we quantitatively analyze the influence of the power capacity after connecting the wind turbine to the system.
