基于传统 N-1 设计标准的电网已不再适用，因为这些设计无法承受极端天气事件或级联故障。微电网系统具有通过紧急情况下的防御或孤岛运行来增强电网恢复能力的能力。本文提出了一个通过分布式风能和太阳能集成规划弹性配电系统的概率框架。我们首先定义弹性分配系统的三个方面，即预防性、生存性和恢复性。然后我们回顾了包含矩估计、机会约束和双向功率流的分布式发电规划模型。我们努力实现两个目标：1）提高电网在灾害袭击后配电线路损坏或断开时的生存能力； 2) 通过积极主动的维护和维修服务加速受损资产的恢复。提供了一个简单的 9 节点网络来演示所提出的弹性规划框架的应用。
Power grids based on traditional N-1 design criteria are no longer adequate because these designs do not withstand extreme weather events or cascading failures. Microgrid system has the capability of enhancing grid resilience through defensive or islanded operations in contingency. This paper presents a probabilistic framework for planning resilient distribution system via distributed wind and solar integration. We first define three aspects of resilient distribution system, namely prevention, survivability and recovery. Then we review the distributed generation planning models that comprehend moment estimation, chance constraints and bi-directional power flow. We strive to achieve two objectives: 1) enhancing the grid survivability when distribution lines are damaged or disconnected in the aftermath of disaster attack; and 2) accelerating the recovery of damaged assets through pro-active maintenance and repair services. A simple 9-node network is provided to demonstrate the application of the proposed resilience planning framework.
