Until recently, the dominant paradigm in the electrification consisted of universal service and its centralization, and for loor modern times think of the power grid of the future where a qualitative and radical leap is required because of the need to manage better energy resources, promote environmental protection and meet the increasingly demanding requirements of quality of service. A power distribution network becomes intelligent acquiring data, communicating, processing information and exercising control through a feedback that allows you to adjust to changes that may arise in actual operation. Ecuador aimed at energy efficiency through smart grids, which allow the dealer to maintain absolute monitoring of energy flow and the elements of the power grid. Thus, it is possible that service companies can efficiently manage their assets and the end user to manage consumption rationally, requiring to enhance the energy efficiency of power grids, one management timely and efficient energy.
