Abstract (EN): This paper presents an approach to the Dynamic State Estimation (DSE) problem to determine the real-time state of an electric power system under quasi-static operating conditions. Bearing in mind the large dimension of power systems, a new DSE algorithm is proposed in order to give a satisfactory solution from the computational point of view for the following steps of the DSE procedure: state forecasting, state filtering and detection and identification of bad data. Simulation results show the performance of the proposed algorithm under different operational conditions: normal, sudden change in the system operating point and occurrence of bad data.
