最近，分布式发电的快速渗透提出了各种问题。其中一个关键问题是频繁的配电网重新配置，这是很难检测的基础上的传统方法。错误的拓扑信息导致错误的控制信号，使得快速变化的智能电网容易越过稳定边界并崩溃。为了确保系统的鲁棒性，我们提出了一个新的数据驱动的重新配置方法，由于最近逐步部署的大型传感器网络在配电系统的公用事业。具体而言，基于信息理论的算法，周刘算法，用于基于配电系统中的假设和验证的证明。仿真结果表明，在IEEE标准分布测试系统中，重构估计具有很高的精度。
Recently, a rapidly penetration of distributed generation raises various issues. One of the key issues is frequent distribution grid re-configuration, which is hard to detect based on traditional approaches. Wrong topology information causes wrong control signal, making fast changing smart grid prone to go over stability boundaries and to collapse. To ensure system robustness, we propose a new data-driven re-configuration approach, thanks to recently progressively deployed larger sensor networks in distribution systems by utilities. Specifically, an Information Theory based algorithm, Chow-Liu algorithm, is used based on a proof for assumption and verification in distribution systems. Simulation results show highly accurate re-configuration estimation in IEEE standard distribution test systems.
