Teste Geométrico no Processamento de Erros da Estimação de Estados Generalizada Desacoplada Rápida

Abstract

This paper proposes the application of geometric tests in the bad data process of the Generalized State Estimation (GSE). The approach allows to determine the source of the bad data, which can be network topology or analog measurement errors, through the combination of normalized residues and geometric test. While generalized approach allows a detailed representation of the network substations, and, consequently, an improved bad data analysis, decoupled techniques are adopted to reduce the computational burden required by the extend network representation. The performance of the proposed algorithm is evaluated through simulations involving the IEEE 14 bus test system, entirely modeled at the bus-section level.
