SCADA and PMU Measurements for Improving Power System State Estimation

Abstract: The state estimator is a fundamental part of the overall monitoring and control systems for power grids. Up to date, in most cases state estimators data are supplied only from traditional supervisory control and data acquisition systems, which collects the real-time measurements from remote terminal units installed in substations. Nowadays, phasor measurement units technology provides more accurate and higher precision real-time measurements than those from remote terminal units. Additionally, phasor measureme… Show more

“…Consequently, attempting a comprehensive replacement would result in severe operational losses. PMUs and traditional SCADA systems will coexist within the power grid [10][11][12]. This gives rise to an intricate scenario, necessitating the monitoring of system dynamics through a diverse array of sensors with varying sampling rates.…”

“…A estimação de estados (EE) é uma ferramenta essencial para a operação de sistemas de potência, segundo Abur and Expósito (2004). Entretanto, devido à introdução de novas tecnologias e o advento do uso das medições fasoriais sincronizadas, a detecção, identificação e correção de erros grosseiros têm se tornado funcionalidades cada vez mais necessárias segundo Salgado et al (2015) e Abood (2020).…”
