The installation of distributed generations (DGs) and energy storages (ESs) in active distribution networks (DNs) could help to increase the resilience of the system. When large scale power outages of urban areas occur, these distributed resources could be used to recover partial, especially the most important loads. However, the determination of boundaries in the distribution networks and the strategy to recover loads are crucial to the overall DN reliability. This paper proposes a framework for resilient distribution network (RDN) to utilize all dispatchable resources to enhance the recovery ability under severe incidents like the complete failure of a substation. Firstly, the idea of restoration areas (RAs) planning with partial recovery is introduced. Each restoration area is schemed to utilize ES, DG and load transfer (LT) to recover loads as much as possible with considering the load importance. The combination weighting method is applied to evaluate the load priority. After that, a dynamic recovery strategy is designed that is valid regarding the actual operation condition and the reliability requirements in distribution system. The flexible boundaries of the RAs can expand or shrink to deal with the uncertainty of power sources output. Furthermore, the load regulation or demand response (DR) is performed to maintain power balance and enhance the overall recovery rate. Finally, illustrative results on IEEE RBTS test systems verify the effectiveness of the proposed model.

考虑分布式资源回收能力的面向弹性的动态配电网络

在有源配电网络 (DN) 中安装分布式发电 (DG) 和储能 (ES) 有助于提高系统的弹性。当城市地区发生大规模停电时，这些分布式资源可以用来恢复部分，尤其是最重要的负荷。然而，配电网络边界的确定和恢复负荷的策略对于整体 DN 可靠性至关重要。本文提出了一种弹性配电网络 (RDN) 框架，以利用所有可调度资源来提高在变电站完全故障等严重事件下的恢复能力。首先，介绍了部分恢复的恢复区域（RAs）规划的思想。每个恢复区域都计划使用 ES，DG 和负载转移 (LT) 在考虑负载重要性的情况下尽可能多地恢复负载。采用组合加权法评价负荷优先级。之后，针对配电系统的实际运行条件和可靠性要求，设计了一种有效的动态恢复策略。RA的灵活边界可以扩大或缩小以应对电源输出的不确定性。此外，执行负载调节或需求响应 (DR) 以保持功率平衡并提高整体恢复率。最后，IEEE RBTS 测试系统的说明性结果验证了所提出模型的有效性。针对配电系统的实际运行条件和可靠性要求，设计了一种有效的动态恢复策略。RA的灵活边界可以扩大或缩小以应对电源输出的不确定性。此外，执行负载调节或需求响应 (DR) 以保持功率平衡并提高整体恢复率。最后，IEEE RBTS 测试系统的说明性结果验证了所提出模型的有效性。针对配电系统的实际运行条件和可靠性要求，设计了一种有效的动态恢复策略。RA的灵活边界可以扩大或缩小以应对电源输出的不确定性。此外，执行负载调节或需求响应 (DR) 以保持功率平衡并提高整体恢复率。最后，IEEE RBTS 测试系统的说明性结果验证了所提出模型的有效性。执行负载调节或需求响应 (DR) 以保持功率平衡并提高整体恢复率。最后，IEEE RBTS 测试系统的说明性结果验证了所提出模型的有效性。执行负载调节或需求响应 (DR) 以保持功率平衡并提高整体恢复率。最后，IEEE RBTS 测试系统的说明性结果验证了所提出模型的有效性。
