A Distributed Newton Method for Power System State Estimation
نویسندگان
چکیده
We propose a fully distributed Newton-type algorithm for state estimation of electric power systems. At each Newton iteration, matrix-splitting techniques are utilized to carry out the matrix inversion for calculating the Newton step in a distributed fashion. In order to reduce the communication burden as well as increase robustness of state estimation, the proposed distributed scheme relies only on local information and a limited amount of information from neighboring areas. The matrix splitting scheme is designed to calculate the Newton step with exponential convergence speed. The effectiveness of the method is demonstrated in various numerical experiments.
