In this paper, aiming to the problems, such as slow convergence, long computing time in the tidal current computation of present medium or large -scale distributed power system, one parallel algorithm based on MPI programming model and the character of distributed power system is given. Then the performance analysis is described. And the algorithm has been programmed in MPICH language. At last,the validity of the algorithm is verified by a middle-scale sample computation on8 CPUs in a small cluster with 128 CPUs.
By applying the canonical correlation decomposition (CCD) of matrix pairs, we obtain a general expression of the least-squares solutions of the matrix equation ATXA = D under the restriction that the solution matrix ...

By applying the canonical correlation decomposition (CCD) of matrix pairs, we obtain a general expression of the least-squares solutions of the matrix equation ATXA = D under the restriction that the solution matrix ∈ Rn×n is bisymmetric, where A ∈Rn×m and D ∈Rm×m are given matrices.
