SUMMARY:

The need for the implementation of policies aimed at energy transition drives the renewable energy sector, prompting increased investments in this field. Globally and nationally, data reveal significant growth in the incorporation of wind and solar energy into power grids, fostering further technological advancements to ensure efficiency and quality in the generation process. This study optimizes a hybrid wind generation system using an Electromagnetic Frequency Regulator (EFR), aiming to minimize electrical losses, reduce component weight, and decrease reliance on secondary sources. The optimization explores the relationship between the number of poles in the generator and EFR, as well as the gearbox transmission ratio. The methodology combines numerical simulations, metaheuristic optimization (Ant Colony Optimization), electric machine design tools, and financial analysis. Results demonstrate that the optimal configuration heavily depends on the pole numbers and gearbox ratio, which directly affect the electrical parameters of the EFR and induction generator. Five topologies were analyzed, with the last proving the most efficient under the proposed criteria. The study provides a scalable methodology to assess the technical and economic feasibility of hybrid systems in diverse locations, contingent on wind data and generator specifications.
