配电网的结构学习和统计估计--II部分

Structure Learning and Statistical Estimation in Distribution Networks - Part II

Deepjyoti Deka, Scott Backhaus, Michael Chertkov

摘要:

本文的第一部分讨论了从节点电压测量中学习电网运行结构的问题。在这项工作中(第二部分),学习的业务径向结构的问题,估计节点的消费统计和推断的线路参数的网格。基于线性耦合(LC)近似的交流潮流方程,多项式时间算法的设计,以完成这些任务,使用现有的节点复杂的电压测量。然后将结构学习算法扩展到缺失数据的情况,其中可用的观测仅限于一小部分网格节点。所提出的算法的有效性证明了通过模拟几个分布测试用例。

英文摘要:

Part I of this paper discusses the problem of learning the operational structure of the grid from nodal voltage measurements. In this work (Part II), the learning of the operational radial structure is coupled with the problem of estimating nodal consumption statistics and inferring the line parameters in the grid. Based on a Linear-Coupled (LC) approximation of AC power flows equations, polynomial time algorithms are designed to complete these tasks using the available nodal complex voltage measurements. Then the structure learning algorithm is extended to cases with missing data, where available observations are limited to a fraction of the grid nodes. The efficacy of the presented algorithms are demonstrated through simulations on several distribution test cases.
