摘要
为优化风电场无功电压控制方案,需要考虑风速差异性及风速预测误差对风电场无功调节能力的影响。提出一种计及风速差异性时风电场无功调节能力的统计分析方法,并量化分析风速差异性和风速预测误差对风电场无功调节范围影响。最后通过算例验证了该方法的有效性。
In order to optimize the reactive power and voltage control scheme for wind farm, it is necessary to consider the influence of wind speed difference and wind speed prediction error on the reactive power regulation capability of the wind farm. This paper proposes a statistical analysis method for the reactive power regulating capability of the wind farm in considering the wind speed difference, and quantitatively analyzes the influence of the wind speed difference and wind speed prediction error on the reactive power regulating range of the wind farm. Finally, the paper illustrates the？effectiveness of the proposed method with case studies.
