The system is analyzed considering the strategic configuration of capacitor and inductor banks, with the primary goal of minimizing operational costs. The allocation of capacitor banks in distribution systems is a strategy employed to reduce energy losses and ensure that voltage remains within the limits set by ANEEL. Furthermore, when these devices are installed in parallel with the network's load, additional benefits can be obtained, such as improving the power factor and increasing system capacity, thereby allowing the integration of more loads. Inductor banks ensure voltage drops where voltage is elevated due to power dispatched by distributed generation. The proposed methodology is based on simulations parameterized by real data, taking into account dynamic and variable factors such as solar irradiation, load demand patterns, and characteristics of different types of distributed generation, also considering the likelihood that Group B (low voltage) consumers may become free consumers, participating in the free energy market. A significant part of this study focuses on the technical and economic feasibility of integrating renewable energy sources, such as solar and wind, as well as other forms of distributed generation, making the simulations more realistic in the current context of electrical grids. The aim is to achieve economic dispatch of distributed generation in the distribution network by allocating capacitor and inductor banks. The results demonstrate effective configurations for reducing operational costs. In conclusion, this study provides valuable insights for planning and managing electrical distribution networks, highlighting the importance of applying new technologies and clean energy sources for the future of energy distribution.
