SEM-MIP based state estimation for topology identification in a distribution network
配电网拓扑辨识是配电系统操作的关键问题和重要前提.由于缺乏足够的量测设备和配电系统拓扑的频繁变化,导致实际的配电网拓扑辨识问题十分具有挑战性.为此提出了基于同步量测数据状态估计的实时拓扑辨识方法.该方法可以利用少量相量测量单元的测量数据准确估计配电网拓扑结构.首先,在配电网中引入结构方程模型(structural equation model,SEM),用于捕捉拓扑与支路电流的关系.然后,针对拓扑辨识问题提出了混合整数规划(mixed integ…查看全部>>
Distribution network topology identification is a key issue and an important prerequisite for distribution system operation.Because of the lack of sufficient measurement equipment and the frequent changes of distribution system topology,the actual distribution network topology identification problem is a highly challenging one.For this reason,this paper proposes a real-time topology identification method based on state estimation of synchronized measurement …查看全部>>
