Brazil is currently going through a delicate moment that requires a transition, which will demand a diversification of its energy matrix in the short term (with obvious consequences for its electrical sector). Evidently, large generation projects require a large time frame to become reality, therefore not qualifying as a solution to the short term problem previously pointed out. One of the main alternatives to contribute with the mentioned diversification is the fostering of the connection of distributed generators to the system, since these generators require a smaller time from the initial project to the start of their operation and use mostly clean and renewable energy sources. Within this context, the present research project has its focus on the analysis of the operation of distributed generators and of their impact over the operation of the bulk power system to which they are connected. This project is structured in three main research topics, which possess an intersection that makes them complementary (in the sense that the achievement of good results for one of them can benefit the development of the others). The topics for research in this proposal are the following:a) Development of control strategies to enhance the efficiency of distributed generators; b) Development of models and tools for the analysis of the operation of elementsof the system; and c) Development of methods for analysis of the impact of distributed generation in the dynamics of the bulk power system. It is possible to observe that the project is structured in such a way that it covers aspects of modeling, analysis and control ranging from the more specific level of operation of a single generator of interest to the more general level of assessing the impact of the operation of several distributed generators over the stability of the bulk power system to which they are connected (which shows the intersection and complementarity previously mentioned in this abstract). Finally, it is possible to state that a successful conclusion of this project can contribute significantly to overcome the technical challenges that are still obstacles for the insertion of an increasing number of distributed generators into the brazilian electrical power system, with positive reflexes for a more general objective that is the diversification of the national energy matrix.
