Energy has been an important economic, political and social factor in the world, especially since the second half of the twentieth century. It is crucial for economic and human development and fundamental to improve the population ́s life quality. In this context, the use of Distributed Generation (DG) of electrical energy has been increased attention, mainly from renewable sources. Despite the generation of solar PV is still considered not economically competitive, this technology has been promoted through governmental programs. Consequently, it has seen a strong growth in its use both in Brazil and in the world. In this study, we investigated the localization methods of distributed generation with energy storage from the point of view of the electrical energy distribution utilities. We chose to use the methodology described by Toledo, 2013 , based on the calculation of the general index (IG). This index is composed of technical, economic and environmental aspects. The economic aspect is composed of the line losses sub-index (IPL) and the load factor sub- index (IFC), the technical aspect of the voltage profile (IPT) sub-index and the reliability (IC) sub-index, and lastly, the environmental aspect is composed of the environmental sub-index (IAMB). In each sub-index was applied a set of weights that have options to value certain aspect. It was proposed to use the pre-selection criteria, in order to identify areas of great or minor interest to install the GD with energy storage, thereby reducing the universe of analysis. The pre - selection criteria were defined as: the distribution grid characterization, location, installation type, connection cost and load priority. For the analyzes we used the software for energy planning, Homer, and PSS ADEPT to calculate the power flow. The five distribution feeders analyzed are located in the metropolitan region of Belo Horizonte, Minas Gerais of the utility CEMIG. It was also analyzed the general simplified index, which is the general index less the sub-indices that depend on the calculation of the power flow, i. e., the line losses and the voltage profile. The analysis consisted of the indication of the optimal locations for the insertion of GD with energy storage. The methodology used was appropriate for the proposed goal, i. e., to determine the optimal locations for insertion of distributed generation with energy storage, from the electrical energy distribution utilities point of view. Finally, some suggestions were proposed for future work in order to improve the methodology.
