摘要

 摘要:随着分布式电源(distributed generation,DG)渗透率在主动配电网(active distribution network,ADN)中不断增加,配电网运行规划难度也不断提高。尤其是故障时配电网形成孤岛运行后,DG出力与负荷需求分配不均,供电效率下降的情况居多。该文针对以上问题对主动配电网故障后孤岛运行展开研究,考虑DG的间歇性出力对其建立概率模型,同时对需求侧负荷进行时序性建模,提出一种基于多时段DG-负荷有功功率平衡的孤岛划分方法。在DG出力不足的情况下,根据负荷优先级和可控度采用遗传算法进行最优切负荷,精准切除优先级低的负荷,保证多负荷、重要负荷供电。最后通过PG&E 69配电网算例验证所提方法的有效性和可行性,结果显示,该方法能在一定程度上有效增加孤岛供电范围。
