Abstract
The bordered block diagonal form (BBDF) of the matrix is useful in parallel computation. In order to develop the coefficient matrix (e.g., the nodal admittance matrix) of power system networks in this form, a new node-ordering algorithm is proposed in this paper. Using this method, the power system is broken down into several smaller components. Within each of these components the decoupled load flow solution can be solved using parallel computing and the results combined to yield the solution of the total system. The performance of the proposed algorithm is compared with that of the conventional methods using the IEEE-57- and 118-bus test systems. Using the proposed method, the number of nodes in each submatrix is more uniform and the computation time for the decoupled load flow solution based on a multiprocessor is less. The results show that the proposed method is adequate for parallel processing on the decoupled load flow solution.
