RESUMO

This work presents a comparison between the performance of dynamic and tracking estimators, in power systems operating under quasi-static conditions, concerning their characteristics of forecasting and filtering. From this comparison, a new dynamic estimator which incorporates the main advantages of the previous estimators is proposed. Also, a new scheme of detection and identification of anomalies (gross errors in the measurements, sudden changes in the system operating point and errors in the network configuration) is presented. This scheme is properly built for dynamic algorithms. Numerical results showing the performance of the new algorithm under different operational conditions are discussed.
