Charge imbalance is common events in electrical distribution systems, which are introduced by the irregular allocation of single-phase loads by the phases that make up the three-phase power distribution. The direct consequence of this imbalance is the drop in operating performance and the reduction in the useful life of network assets (transformers, cables, etc.), as well as affecting the quality of energy distributed from a product standpoint over distances from active sources of the distribution circuits, therefore voltage drops are present. The technique used to correct voltage drops is to redistribute the loads more evenly, but this activity is not an easy task and almost always the effectiveness of the way it is performed in most utilities is questionable, including incurring infringement claims. Quality indicators are inadequate supply voltage level at delivery points and customer connection. The model proposed in this work has the aid of the load-balancing task, using a fuzzy logic tool for the interpretation of the dynamic behavior of the loads connected in the system and the optimization of the best allocation of single-phase consumer units with an algorithm based on the simplex model. Both decisions making with fuzzy logic and distribution were simulated with data provided by the local concessionaire Eletrobras Amazonas through the grid management system.
