Abstract
Hybrid systems are those that use two or more sources of energy for electricity generation, that is, they are able to use simultaneously two types of resources, for example, solar and wind energy. The use of this mechanism has been widely used due to the need of using alternative and renewable forms of energy, besides of the efficiency in integrating new or traditional systems. One of the main characteristics of this system is the possibility of complementation: a photovoltaic component for periods when the wind does not blow or blow at low speed, and a wind turbine for the rainy or cloudy periods. Thus, the objective of this work is to perform a technical and economic analysis of the implantation of a photovoltaic an a solar-wind hybrid system to cover the electric power demand of a student residence in Itajubá, Minas Gerais, Brazil, and analyze which system is most economically attractive. The methodology used to develop this work will be based on data collect of solar radiation and wind speed in the chosen town, also in the system sizing, and the technical and economic feasibility for its implementation. The economic analysis includes the calculation of IRR, NPV and Payback, taking into account the sale of surplus electric energy using the system of compensation of electric energy credits according to resolution 482/2012 of ANEEL. The photovoltaic system was the most economically viable due mainly to the local wind profile.
