Ubicación óptima de dispositivos de compensación reactiva para la mejora del perfil de voltaje y reducción de pérdidas en el sistema eléctrico de potencia utilizando técnicas de clusterización

Abstract

This paper presents a method to locate SVC compensators in the SEP, using a clustering methodology. For which, we start by quantifying the OPF where the sensitivity matrix of the system is determined from the Jacobian of the system. Subsequently, the electrical distance and attenuation array is generated. Subsequently, the first cluster identification criterion calculated together with the k-Means clustering technique is used. In this way, the voltage control zones (VCA) are obtained. Also, the SVC installation cost minimization criterion is used to determine the best arrangement of the compensators. The described approach is tested on the 14-node and 39-node system. Furthermore, the obtained results are compared with the Power Factory software and similar research. In conclusion, the suggested approach is useful for the creation of VCA, as well as for finding the best arrangement of SVC equipment. However, it is critical to consider the capacity of the compensators, since an excessive value of the SVC capacity causes a higher number of losses.
