Ubicación óptima de sistemas fotovoltaicos en redes de distribución usando el método de búsqueda armónica

Abstract

This article shows a viable solution to locate optimally units of Distributed Generation (DG) of the photovoltaic type, in a system of electrical distribution. For this, the 9-bar electrical distribution system is used, taken from the Institute of Electrical and Electronic Engineers (IEEE). Consequently, the process allows the study of power flows applied in the system, obtaining in this way, the values of voltage and power in each bus of the system. Afterward, a node of the system is randomly selected to find a partial solution through the harmony search algorithm, which will perform this quest, iterating the necessary nodes until reaching the desired convergence. The harmony search algorithm calculates the emplacement power which is corresponding to each node, and allows the compensation its nodal voltage; furthermore, the harmony memory of the logarithm, which archives the three results with greater relevance, compares these partial results to be presented on the whole by a trend line, which in turn shows the results with the initial voltage profile of the electrical system without having made any implementation of generation. Accordingly, this method allows to appreciate the elevation of the voltage profile in the link node, and also in the distribution system, for the system perceives this energy supply elevating the nodal voltages of the electrical system.
