摘要: 为最大限度保障风电消纳,在规划论证风电装机规模过程中,有必要定量分析风电装机规模与弃风率、消纳风电电量占全社会用电量比重等指标之间的关系。提出年最大弃风电量的概念,基于风电出力和负荷持续曲线,提出了一种计算年最大弃风电量方法,并根据对持续曲线的近似,推导了年最大弃风电量的估算公式;计算最大弃风率与风电电量保证消纳比例等指标,可为风电规划设计提供参考。最后,通过算例分析验证了该方法的有效性。

Abstract: In order to guarantee the wind energy consumption, it’s necessary to analyze the relationship between the installed wind power capacity and the wind curtailment rate, the proportion of wind energy consumption to the total electricity consumption, during the wind power planning phase. This paper proposed a concept of maximum annual wind energy curtailment. Based on the output of the wind power and the load duration curves, a method for computing the maximum annual wind energy curtailment was proposed. With the maximum annual wind energy curtailment, an estimation formula was derived to obtain the indices like the maximum wind energy curtailment rate and the guaranteed wind energy consumption rate. And this can be seen as the reference for wind power planning and design.Finally, the effectiveness of the proposed method was verified in the case study.

Key words: wind power generation, wind energy consumption, wind energy curtailment, duration curves
