A complex network analysis of the Brazilian Power Test System

Abstract

This paper presents a complex network analysis of the Brazilian Power Test System (BPTS), which is based on the real Brazilian electric power system. The aim is to model the BPTS cases via graphs, characterize them according to existing complex network models, compute several invariants from graph and complex networks, and analyze them with respect to these invariants, in order to obtain useful information for the application. The analysis of these metrics applied to the electrical power system can help us to identify and solve problems such as network overload, catastrophic failures and blackouts. Each invariant leads to different critical nodes. Thus, we could look for the best combination of invariants and weights to analyze power system networks.
