Massive Jacobi power flow based on SIMD-processor

Abstract

This paper presents an implementation of the Jacobi power flow algorithm to be run on a single instruction multiple data (SIMD) unit processor. The purpose is to be able to solve a large number of power flows in parallel as quickly as possible. This well-known algorithm was modified taking into account the characteristics of the SIMD architecture. The results show a significant speed-up of the algorithm compared to the time required to solve the algorithm in a conventional CPU, even when a more efficient sequential algorithm, such as the Newton-Raphson, is used. The accuracy of the performance has been validated with the results of the IEEE-118 standard network.
