Reconfiguración óptima de redes de distribución que contienen generación distribuida hidroeléctrica, aplicando un algoritmo de optimización basado en colonia de hormigas

Abstract

In this work, a methodology is developed to solve the problem of reconfiguration of electrical distribution networks using the ant colony algorithm. The presented methodology has the advantage of always finding feasible solutions considering the radial topology of the network. The objective function of the reconfiguration of the distribution network is to minimize active power losses of the lines, subject to the restrictions of radial topology, voltage range in the nodes, and electrical current of the lines. The distribution network reconfiguration algorithm is applied to two electrical networks with and without distributed hydroelectric generation, IEEE 34 nodes network and a real network. For the simulations of distributed generation, synchronous generators connected to network nodes are used. The effect of the distributed generation source in the network is analyzed. Additionally, the algorithm is validated on the standard electrical distribution networks of 33 nodes and 69 nodes, obtaining the optimal for both networks. The power flows of the electrical distribution networks are carried out in OpenDSS and the algorithm is programmed in MATLAB, for which communication between the two programs is established
