Computational model for the analysis of distributed generation in systems including smart grids

This work presents a simplified computational model for the analysis and the optimization of distribution networks considering the presence of smart grids. The determination of bus voltages and branch currents is based on a linear approximation, which allows to evaluate the impact on the network resulting from the connection of different distributed generation sources (DG). One of the main advantages of the proposed model is the convergence for any operation condition. Furthermore, it is possible to apply the model to problems concerning the operation and expansion of smarts grids. Finally, to test and validate the model, it was applied to an existing distribution network composed of 135 buses and with distributed generation. The main results are presented and discussed.
