Topological Analysis

Definition

Topological analysis is a method used to examine the structure and interconnectivity of a network, focusing on the relationships and configurations among its components rather than their physical properties. In the context of state estimation, it helps identify potential anomalies or inconsistencies in data collected from various points in the network by analyzing how different nodes are connected and how information flows between them.
