Modelagem e Simulação do Sistema de Controle Central para uma Microrrede

Abstract

The modern society has a greater need for reliability and quality of energy supply. The growing evolution of distributed generation has aroused the interest of the scientific society due to contributions in the same direction. The microgrids make use of renewable energy sources, energy storage systems, and the diverse features of the distribution network operating as a single system. In this work we present a modeling of a central controller to microgrids, operating in connected or island mode of the electric network. This modeling is based on the Enel Distribuição Ceará microgrid pilot project, installed in a condominium of residential houses. The technical description of the project, the proposed architecture and the definition of the requirements are presented. Through modeling it is possible to simulate and identify design errors before implementation and better analysis of network operation procedures. It also makes it possible to analyze model performance by performing various simulations to obtain reliable data in order to have an accuracy of the obtained estimates. The development methodology uses the mathematical language Colored Petri Nets for the modeling of the central system, allowing simulations and structural and behavioral analysis.
