Abstract The intelligent microgrids are an efficient alternative that allows to supply the demand, decreasing the losses of the electrical system at the same time; the environment and the consumers are the main beneficiaries. This article develops a heuristic based on an energy management model based on the real price of electricity, which will allow end users to encourage the implementation of a policy of response to demand in order to optimize their consumption In order to do this, a micro smart grid is analyzed, with conventional and non-conventional renewable generation. In addition to this, a mechanism of "real energy price" will be implemented as a policy of response to demand, aiming to optimize the costs of energy that will be transferred to users depending on the stratum of which it belongs; these costs will have a short-term horizon with hourly intervals, achieving a reduction in the purchase of energy from the system.
