Dynamic state estimator using ANN based bus load prediction

This paper presents an algorithm for dynamic state estimation of a power systems. The method uses ANN based bus load prediction for the prediction step in the DSE. The proposed DSE uses rectangular coordinate formulation for measurement equations. A second order dynamic state estimator which incorporates the full nonlinearities of the measurement function is used for the filtering step. The inclusion of nonlinearities makes the proposed state estimator perform better in case of sudden large changes in load/generation
