A Research On Parallel Power Flow Of Power System Based On MPI In Cluster Of PCs Environment

The parallel power flow calculation is an important method to enhance the speed of multiple data power flow operation, And it is the low-cost, high efficiency project proceeded in a cluster of PCs. This paper firstly introduced the basic theory of parallel algorithms, and then discussed the cluster of PCs system and MPI. According to this theory, an appropriate laboratory environment, a simple cluster of PCs based on WINDOWS2000 and MPI, was established. There are great differences between the newly devised MPI Programming mode and the traditional one. Secondly, this paper discussed the method how to proceed the MPI parallel programing in cluster environment and how to implement the IEEE-30 and IEEE-118 nodes power system MPI parallel power flow calculation. The time differences between Parallel power flow and traditional one were analysed after this program was tested. In addition, the effects of parallel efficiency caused by network communication in parallel power flow and traditional one were also compared. Finally, from the theoretic and practical study, the feasibility of proceeding parallel power flow calculation in cluster of PCs was discussed and some meaningful conclusions were also achieved.
