【摘要】 作为配电网中的关键灵活性资源,远程可控制开关(RCS)和移动式应急电源(MEG)对于配电网韧性水平的提升具有重要作用。然而,目前的相关研究主要关注的是故障线路被精确隔离后的负荷恢复过程,并未考虑故障隔离期间配电网所受的影响。为此,提出了考虑MEG事故前优化配置的配电网两阶段重构韧性提升方法,通过在事故前配置MEG并形成多个MEG孤岛,提升配电网的抵御能力,并在事故后,通过RCS的快速动作和已配置的MEG快速恢复负荷。最后,采用了IEEE33节点配电网络验证了所提方法的有效性。更多还原

【Abstract】 As key flexible resources in distribution networks,remote controllable switch(RCS)and mobile emergency generator(MEG)play important roles in enhancing the resilience of distribution networks. However,existing studies mainly focus on the service restoration stage after faulted lines are precisely isolated,usually the impacts of fault isolation stage on distribution networks are neglected. Two-stage reconfiguration method for resilience enhancement of distribution networks is proposed considering the optimal pre-positioning of MEGs. By positioning MEGs and forming several MEG islands before extreme natural disasters,the ability of distribution networks to resist extreme natural disasters can be enhanced. After extreme natural disasters,RCSs and positioned MEGs can quickly recover the load which is out of service. Finally,the IEEE 33-bus distribution system is employed to verify the effectiveness of the proposed method.更多还原
