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 is evaluated on a series of test systems. The test results show that the parallel algorithm parallel algorithm can greatly reduce the running time and get great speed-up factor and efficiency.
