An Orthogonal Row Processing Algorithm for Power System Sequential State Estimation

  title={An Orthogonal Row Processing Algorithm for Power System Sequential State Estimation},
  author={A. Simoes-Costa and V. H. Quintana},
  journal={IEEE Transactions on Power Apparatus and Systems},
In this paper a sequential algorithm for power system state estimation based on the use of Givens rotations is investigated. The fact that the rotations are orthogonal transformations assures the numerical stability of the algorithm. The Jacobian matrix is processed one row at a time, and sparsity can be easily exploited. Also, the method presents some features which are advantageous from the point of view of bad data detection, identification and elimination. Both the description and the… CONTINUE READING
