Abstract

While the graph theoretic properties pertaining to the electrical grid are well known, the field of graph signal processing offers new insights and understanding about the measurements from the electrical grid. In this paper we establish that voltage measurements are the result of a low-rank excitation to a low-pass graph filter. Then, we illustrate the identification of community structure in the electrical gridsincetheexcitationsarelow-rankinnature. Proposed algorithm for community detection is tested on a synthetic 2000 bus test case in the state of Texas with promising results.
