Title: | Distributed Gauss-Newton method for AC state estimation: A belief propagation approach | Authors: | Cosovic M. Vukobratović, Dejan |
Issue Date: | 8-Dec-2016 | Journal: | 2016 IEEE International Conference on Smart Grid Communications, SmartGridComm 2016 | Abstract: | © 2016 IEEE. In this paper, we propose a solution to an AC state estimation problem in electric power systems using a fully distributed Gauss-Newton method. The proposed method is placed within the context of factor graphs and belief propagation algorithms and closed-form expressions for belief propagation messages exchanged along the factor graph are derived. The obtained algorithm provides the same solution as the conventional weighted least-squares state estimation. Using a simple example, we provide a step-by-step presentation of the proposed algorithm. Finally, we discuss the convergence behaviour using the IEEE 14 bus test case. | URI: | https://open.uns.ac.rs/handle/123456789/3849 | ISBN: | 9781509040759 | DOI: | 10.1109/SmartGridComm.2016.7778834 |
