Abstract
Small-scale wind turbines offer a promising solution for distributed renewable energy generation. However, this approach often leads to wasted energy when battery capacity is reached, as excess energy is typically dissipated into resistors. The reliance on batteries further increases the cost and complexity of such systems. This paper presents a nonlinear control algorithm for regulating buck-type converters, providing a more efficient energy management solution. By employing a grid-connected inverter, excess energy is utilized rather than dissipated, potentially eliminating the need for batteries and reducing micro-wind turbine installation costs. The proposed control strategy manages the DC-link voltage for the inverter by compensating for variable wind conditions, managing fluctuations in both frequency and magnitude for optimal performance. The effectiveness of this approach is validated through both analysis, simulations, and real-world implementation, demonstrating superior performance compared to conventional systems and addressing key limitations of existing linear controllers.
