摘要(Abstract)：

分布式电源(distribution generation,DG)在配电网的大量接入,形成主动配电网(active distribution network,ADN),对配电网的规划调度运行产生了深远影响,特别是给配电网应急恢复带来新的问题。针对这个问题,提出一种面向主动配电网的故障状态下的负荷转供模型,有利于提高供电可靠性和经济性。首先,根据可控能力对DG进行分类,并提出利用可控DG发电来恢复对越限负荷供电的策略;其次,提出负荷转供优化模型,综合考虑了DG发电和配网重构来降低供电企业综合负荷转供成本;再次,提出一种基于图论的重构配网放射性快速判断方法,能够为遗传算法快速产生可行解并排除不可行解的干扰;最后,仿真算例结果显示,提出的模型和方法在计算速度、迭代次数上优于现有研究方法,且可增加DG的额外发电和降低网损。
