具有分布式发电（DG）的微电网在配电系统由于自然灾害而发生重大故障的情况下提供了弹性解决方案。本文提出了一种新的配电系统的操作方法，形成多个微电网供电的分布式电源从径向配电系统在实时操作，以恢复关键负荷停电。具体而言，一个混合整数线性规划制定最大限度地提高临界负荷被拾起，同时满足自自足和操作约束的微电网形成问题，通过控制的ON/OFF状态的远程控制开关设备和DG。设计了一种分布式多智能体协调方案，通过本地通信的全局信息发现作为优化的输入，这是适合于灾难性事件后的自主通信要求。所形成的微电网可以进一步用于电力质量控制，并且可以在主电网的恢复完成之前连接到更大的微电网。基于改进的IEEE分布测试系统的数值结果验证了我们提出的方法的有效性。
Microgrids with distributed generation (DG) provide a resilient solution in the case of major faults in a distribution system due to natural disasters. This paper proposes a novel distribution system operational approach by forming multiple microgrids energized by DG from the radial distribution system in real-time operations to restore critical loads from the power outage. Specifically, a mixed-integer linear program is formulated to maximize the critical loads to be picked up while satisfying the self-adequacy and operation constraints for the microgrids formation problem by controlling the ON/OFF status of the remotely controlled switch devices and DG. A distributed multiagent coordination scheme is designed via local communications for the global information discovery as inputs of the optimization, which is suitable for autonomous communication requirements after the disastrous event. The formed microgrids can be further utilized for power quality control and can be connected to a larger microgrid before the restoration of the main grids is complete. Numerical results based on modified IEEE distribution test systems validate the effectiveness of our proposed scheme.
