SUMMARY This paper proposes an index, called Undetectability Index (UI), to classify the measurements according to their characteristics of not reflecting their errors into the residuals of the weighted least squares state estimator (WLS) from a geom

Os centros de operação de sistemas elétricos de potência (SEP) exigem que uma vasta quantidade de informações esteja disponível para o controle e supervisão dos SEP. Em uma operação segura dos SEP é de suma importância que o processo de e

This paper presents a new insight to design reliable metering systems for state estimation purposes based on the Undetectability Index (UI). Gross errors in measurements with high UI are very difficult to be detected by methods based on the analysis

In this paper, a new algebraic-graph method for identification of islanding in power system grids is proposed. The proposed method identifies all the possible cases of islanding, due to the loss of a equipment, by means of a factorization of the bus-

A partir de uma análise geométrica, do estimador de estado por mínimos quadrados ponderados, propõe-se, neste trabalho, um índice para classificação das medidas de acordo com as suas características de não refletirem grande parcela de seus e

In this paper, a new fast method for identification of islanding in power system grids is proposed. This method identifies all the possible cases of island formation, due to the loss of a single equipment (criteria N-1), by means of a single factoriz

The Jacobian matrix of the power flow equations become singular at the maximum loadability point and problems of non convergence are observed due to ill-conditioning. The Jacobian of the state estimation formulation also becomes singular at the maxim

In this paper, a geometrical based-index, called undetectability index (UI), that quantifies the inability of the traditional normalized residue test to detect single gross errors is proposed. It is shown that the error in measurements with high UI i

This paper proposes a new algorithm that enables observability analysis (restoration and identification of observable islands) and identification of Critical Measurements and Critical Sets for observable or unobservable systems. The proposed algorith
