Abstract: Size of the distribution and transmission networks to be planned or to be monitored in online systems is increasing significantly. The number of nodes of a complete distribution system exceeds several hundred thousand. As a consequence, efficient methods for the calculation of such a system are required. On the other hand, architecture and computation power of modern computers is not always used in an efficient way. In this paper, an approach using Single Instruction Multiple Data instructions and multiprocessing is proposed, taking a symmetrically constructed but unbalanced loaded distribution network as a used case for a power flow calculation.

Keywords: symmetrical components; multiprocessing; OpenMP; real time; parallel programming; SIMD; single instruction multiple data; basic linear algebra subprograms; sparse matrix; C++; power flow algorithms; symmetrical distribution networks; unbalanced loading; distributed systems.
