配电网状态估计（SE）工具的发展受到越来越多的关注，因为传统的被动配电系统已经变得更加积极。配电系统模型的高维性可能导致非常高的计算时间。本文针对这些问题，并提出了一种SE算法，该算法分析了已被分割成重叠区域的网络，使该算法的并行应用。该算法的开发，以提供与配电系统的要求兼容。该算法的新奇之处在于它的能力，以产生可行的解决方案的电压估计与一个更小的数量的真实的测量。所提出的算法被称为重叠区的方法，并已在356和711节点网络上进行了测试。
The development of state estimation (SE) tools for distribution networks is receiving increased attention as the traditionally passive distribution systems have become far more active. The high dimensionality of a distribution system model may lead to very high computation times. This paper addresses these issues and proposes an SE algorithm that analyzes a network which has been split into overlapping zones, enabling parallel application of the algorithm. The algorithm is developed to provide compatibility with distribution system requirements. The novelty of the algorithm lies in its capability to generate feasible solutions for the voltage estimation with a much smaller number of real measurements. The proposed algorithm is referred to as an overlapping zone approach, and has been tested on 356 and 711 node networks.
