OPERATIONAL ANALYSIS OF A DISTRIBUTION NETWORK FOR ITS POTENTIAL CONFORMATION OF MICRORNETS

Abstract

Electrical energy distribution networks constitute complex structures made up of a very large set of electrical equipment and linking circuits. Recent advances in power electronics, communication and computing have given rise to the concept of Smart Grid, where developments are aimed at improving the technical and economic operational efficiency of the network, reducing the impact on the environment, take advantage of sources based on renewable energy and improve the quality of supply to consumers. In this context, the convergence between distributed generation and distribution networks, in the microgrid format, emerges as a proposal for consideration. The present work aims to evaluate the performance of a standard distribution network in static conditions of normal and emergency network, and establish a criterion to define and differentiate potential microgrids. Annual energy balance studies are carried out on each microgrid, statistical collection of extreme peak and valley demands, and critical supply nodes. The results obtained constitute the basis for the future study of management strategies of a system of interconnected microgrids in an exchange market. A portion of the 13.2 kV distribution network of the city of Rafaela, Province of Santa Fe, is used as the study system.
