| Abstract: | The paper presents a parallel algorithm for solving the large scale power system power flow calculation problem.The proposed approach is based on Message Passing Interface and P-Q analysis method power flow calculation.The task of the power flow calculation is partitioned to a few smaller pieces and occupied to multi-processors to be dealt with simultaneously based on the MPI.The parallel algorithm is evaluated on a series of test systems.The test results show that the parallel algorithm can greatly reduce the running time and get great speed-up factor and efficiency. |
