The increasing use of renewable energy to produce electricity, including photovoltaic, is an alternative used to meet growing electricity demand. Particularly, has been discussed the possibility of inserting these sources associated to loads, which is related with the concept of micro grids. A simulation model that allows to determine the behavior of the PV system, connected to the micro grid in different weather conditions, is essential to validate and predict future problems that may exist. Thus, this paper proposes a simulation model of a photovoltaic system, which includes the representation of the inverter and a bidirectional converter with storage unit, allowing the insertion of photovoltaic in a micro grid in steady state under different conditions of solar irradiation. The results show the behavior of the micro grid to different environment conditions of irradiation, different values of loadsconnected to the node generation and behavior of bidirectional converter, as in the storage of electrical for the conditions simulated. The behavior of the PV system as a source of energy within a micro grid was analyzed by simulating different load values, irradiation and electrical characteristics of the micro grid.
