Alocação ótima de geração distribuída fotovoltaica para redução de perdas de energia em sistema de distribuição de energia elétrica: um estudo de caso

Abstract

The current change on regulatory laws and economic scenario, as well as the electrical system flexibility, and the need to protect loads against network disturbances are boosting the development of a system based on new technologies for example distributed generation (DG). The study presents the analysis of the impacts on the voltage profile and losses when a new Distributed Generation (DG) source is inserted into the system. Therefore, was considered a test system in the northwest of the state of Rio Grande do Sul using 80 bus, and some scenarios of insertion of Micro and Mini Distributed Generation. The system was modeled in the ATP Draw software, and from the data obtained from the radial system, different scenarios were chosen to insert distributed generators and to analyze the voltage profile and the losses in the system. Results obtained with this study were able to demonstrate the importance of the optimal location for the reduction of impacts, and for future papers are expected to analyze heuristic and deterministic techniques for the optimal allocation of DG.
