Abstract

The classic distribution systems operate as radial systems, which means that the power flows in only one way: from the substations to the consumers and there is only one active electrical circuit connecting those two points. There are, however, tie switches (normally open switches) that, when closed, change the electrical circuit allowing the loads to be supplied by a different feeder or branch. Besides the reliability incensement, by correctly using the tie switches it is possible to reduce the technical power losses and improve the consumer’s voltage magnitude. The distribution systems’ reconfiguration is a very complex problem due to the infinitude of possibilities, thus a common solution is to apply metaheuristic routines. This work presents the implementation and comparison of two metaheuristic routines developed to solve the reconfiguration problem in distribution systems considering the insertion of distributed generation. The paper presents the results of 16 and 33 bus test systems.
