Electricity as an energy resource acquired vital importance in modern society because it allows relatively easily meet the demand for their services. Thus the demand for electricity increases with the evolution of populations who benefit from. The electrical system that produces this input is limited in its ability to available resources for generation, transmission and distribution. Roughly speaking this limit is set by the maximum power of the system. This maximum power can be achieved at certain times of the day, called peak hours and in most of the time the system is under utilized. Having the ability to control demand, you could use that excess capacity by transferring loads to more favorable times. For this there must be a coordinated action of many consumers to obtain operating results. Coordination would then be obtained through socalled smart grids that add functions and automation with various levels of complexity and constitute a very large system that binds generation to consumption. The noticeable difference is in the residential consumer of this fact be included in the operation of this network in near real time, or is awaiting more effective participation in the electrical system. One of the means designed to achieve this effect is through tariff incentives, where the variation of the energy cost would motivate consumers to change their consumption habits. To participate in this system the residential consumer needs to adapt its facilities to operate more efficiently by getting the maximum power at the lowest cost. It is not often that changing habits is the power of consumer, so it needs the means to adapt their electrical installations to this reality. Adaptation involves incorporating means for storing and managing energy resources so that the installation provides energy services at the time that is required, regardless of the time it purchases the necessary inputs. This requires, beyond the means of energy storage, as a control, given that residential consumers should not live according to their electrical out lets. This system would consist of standalone automatic elements derived from those used in industrial automation electrical control circuits. Therefore the aim of this work is to analyze the potential application of so-called smart electric devices (meters and control elements) in the automation of residential electrical installations and their interaction with the smart grid.
