The focus of this project is the development of a computational system for the reduction of losses in energy distribution networks (urban networks) by means of advanced computational algorithms of circuit reconfiguration. The results deriving from the application of this system should be, among others, an increase in billing for the energy distribution companies and better use of the energy generated in the country. It is estimated that the Brazilian energy distribution segment dissipates 52 per cent of the total losses of the system, at an annual cost of around 1.5 billion dollars. The development of computational algorithms to reduce these losses by means of the reconfiguration of the network is extremely complex. In this context, it is proposed to apply the Evolutionary Algorithm with Representation in Graph Chains (EA with RGC) (Delbem, 2002), to solve the problem. EA with RGC has proved to be capable of drawing up adequate restructuring plans for relatively large networks, using small computing times. Besides this development, an efficient man-machine interface is extremely important to drive the work with a large quantity of data generated by a distribution system and to facilitate the interpretation (assessment) of the solutions proposed by the system. The proposed interface is based on Virtual (immersive) Environments, which have brought about huge revolutions regarding man-machine relationships both in the solution of scientific problems as well as industrial ones.
