RESUMO

Technical energy losses in primary distribution networks are due to electrical resistances in lines. Due to reactance of power lines and inductive nature of some loads, part of the energy dissipated is due to reactive power that travels back and forth in lines, all the way from power sources to load points. Capacitors installed near load points can provide local complementary reactive power that decrease losses. This work presents conceptual and implementation innovations that allows to rescue the dynamic programming approach for the capacitors sizing and allocation problem in distribution networks, for fixes and variables loads. The work also presents two approaches to the capacitors control problem. The first approach is the development of a complex adaptive system (a classifier systems). The second approach to the capacitor control problem is a specialization of dynamic programming concepts, developed for the capacitors placement problem. Case studies in large real networks illustrate the possibilities of the developed methodologies.
