Power generation from renewable sources, especially wind power, has emerged as a crucial and sustainable alternative to meet current and future energy demands. The objective of this research was the modeling, design and control, design and control of an electronic system that would allow the connection of a turbine to a direct current busbar in a home microgrid in a context of energy efficiency, considering the variability of the wind. The methodology used consisted of establishing the mechanical and electrical characteristics of the Wind Generation System have been established in order to determine the necessary expressions in the modeling and design of the SEPIC converter (Single-Ended Primary Inductor Converter), to then delve into the design of the current and speed controllers under the optics of two different control techniques: linear PI (Proportional-Integral) and non-linear PBC + PI (Passivity-Based Control with Proportional-Integral action). These controllers were integrated with a speed MPPT (Maximum Power Point Tracking) stage based on the P&O (Perturb and Observe) algorithm, subject to the fixed pitch variable speed strategy. The results obtained were to propose a methodological guide that demonstrated its effectiveness and efficiency by maintaining the system around the maximum power point when subjected to different wind conditions. In addition, the control techniques demonstrated their flexibility for integration into renewable energy, increasing the reliability of the systems. The non-linear control was highlighted by having a faster response, allowing the MPPT to generate more references generating less stress on the turbine shaft. The PBC theory allowed control over the currents in the converter inductors. Finally, it is concluded that the SEPIC topology demonstrated its versatility by allowing the control of higher power systems.
