Estratégia de reconfiguração de redes de distribuição com recursos distribuídos via algoritmos genéticos

Abstract

The Brazilian distribution system is in a phase of changes, with a focus on intelligent electrical networks, in which the concept of intense use of information and communication technologies is being studied. The expression smart grid, is a new reality imposed on electricity services, entering this scenario distributed generation sources, storage systems and measurement systems working in an integrated way, all in a network with self-healing power. This work proposes the analysis of the reconfiguration of electrical networks in modern distribution systems, making use of distributed generators and energy storage systems. For this, the best topology of the electric network operation is defined with the objective of minimizing energy losses by making genetic algorithms. Unbalanced load models were considered for the analysis, with different behavior as a function of the applied voltage. The studies were carried out in an IEEE 123 busbar test system through the OpenDSS and MATLAB interface.
