A Geometrical View for Multiple Gross Errors Detection, Identification, and Correction in Power System State Estimation

A two steps procedure in state estimation gross error detection, identification, and correction

“…The innovation index, II i , was proposed as a manner to convert the measurement residuals to the errors, using the geometrical view of state estimation [18,20], as presented below.…”

“…In what follows the presentation of the masked error and its recovering for state estimation purposes will be presented [13,20].…”

“…More recently, using topological and geometrical approaches Bretas et al [10][11][12][13][14][15][16][17][18][19][20], have proposed methodologies that beyond having the classical SE functions it also composes the error and then correct the magnitude of the measurements in error.…”

A gross error detection method based on 3MAD–GRW–MMMD

“…In general, the measured data errors are separated into random errors and gross errors [1][2][3][4] in data reconciliation. Because the random error is inevitable and follows a certain statistical regularity, there has been many established successful algorithms to deal with it.…”

Processamento de erros grosseiros através do índice de não-detecção de erros e dos resíduos normalizados

“…Fazendo uso também de uma análise geométrica dos resíduos do estimador de estado WLS, em BRETAS et al, 2013), métodos para processamento de EGs foram propostos. Entretanto, apresentam ainda dificuldades para processamento de EGs múltiplos interativos.…”
