Abstract

Abstract: 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。
