Dynamic State Estimator using three parameter exponential smoothing technique

This paper presents a new scheme of Dynamic State Estimation (DSE) employing three parameter exponential smoothing technique to depict the time evolution of the power system states at the prediction step. To resolve the filtering problem it utilizes the efficient Extended Kalman Filter (EKF). The proposed scheme of DSE has been tested on IEEE 5-bus, 14-bus, 30 bus and 57 bus test systems. The test results have been compared with the same from some well known existing DSE schemes. The analysis of the results proves the supremacy of the proposed method over the traditional ones.
