Modern power systems analysis becomes more challenging due to their increasing complexity, greater interConnectivity of elements and sub-systems and the use of alternative generation systems, among others. In order to efficiently conduct these analyses, it is necessary the use of modern computational and numerical techniques, such as parallel processing and fast periodic steady state solution techniques...
In this paper, the application of a parallel processing technique in order to obtain a more efficient version of an analytical method for estimation of voltage sags in electric power systems is presented. The algorithm was written in C programming language and performed using the GNU/Linux operating system The parallelization of the analytical method is made by using multi-thread programming (POSIX...
In this paper, the parallelization of the Fault Positions Method for the stochastic assessment of voltage sags is presented. Using the GNU/Linux operating system, an algorithm was written in C programming language which exploits multi-thread programming by including functions defined by the POSIX threads header and library, in order to perform parallel calculations. A comparative analysis of the parallelized...
Modern advances in computer technology will definitely have a great impact on the methodologies used in the expansion and operational planning of power systems. Parallel and distributed systems are the new tendencies in technologies that present a great potential for application in these areas. Graphics processing units (GPUs) have recently become popular in several fields of science due to their...
This paper deals with the implementation of parallel processing SPWM multilevel techniques through programmable gate arrays (Field Programmable Gate Arrays, FPGAs). It is shown that switching losses in power converters significantly decreases with an increased number of levels in the SPWM signal, thus providing an efficient energy transfer. The multilevel SPWM control response of 3, 9 and 21 levels...
