This paper presents the application and use of a methodology based on fuzzy theory and simulates its use in intelligent control of a hybrid system for generating electricity, using solar energy, photovoltaic and wind. When using a fuzzy control system, it reached the point of maximum generation of energy, thus shifting all energy generated from the alternative sources-solar photovoltaic and wind, cargo and / or batteries when its use not immediately. The model uses three variables used for entry, which are: wind speed, solar radiation and loading the bank of batteries. For output variable has to choose which of the batteries of the battery bank is charged. For the simulations of this work is used MATLAB software. In this environment mathematical computational are analyzed and simulated all mathematical modeling, rules and other variables in the system described fuzzy. This model can be used in a system of control of hybrid systems for generating energy, providing the best use of energy sources, sun and wind, so we can extract the maximum energy possible these alternative sources without any prejudice to the environment.

Given the current energy crisis experienced in our country with the lack of rain in some areas, the energy distributors were forced to resort to thermal power plants to complement their energy production; raising the cost of electricity generation, they have been forced to repass this value to the customers through the Tariff Flags. Concerned about a substantial increase in their electric bill, some consumers were forced to look for alternatives so that their results are not affected. The use of diesel generation at peak hours is a relatively simple and inexpensive alternative that has been widely used for several industrial, commercial and service customers. In this present work, we conducted a feasibility study of the use of diesel generators at peak hours in a medium-sized hospital, calculating the depreciation period for the investment through savings in electricity bills
