Wind Energy Conversion Systems Control Strategies

Wind energy conversion systems rely on sophisticated control strategies to optimise power capture, ensure mechanical integrity and comply with grid requirements across a wide range of operating conditions. Core methods include aerodynamic regulation via blade pitch and stall control, which respectively adjust or exploit blade angles to limit loads in high winds, and speed-based approaches that maintain turbines at the optimal tip-speed ratio through variable-speed generation. Power electronics play a central role in linking the generator to the grid, employing cascaded converter stages and advanced controllers for both generator-side and grid-side converters. Maximum power point tracking algorithms form the backbone of many variable-speed controls, dynamically seeking the turbine’s most efficient operating point. Recent advances extend classical proportional–integral schemes to robust nonlinear techniques such as sliding mode control and model predictive control, offering improved disturbance rejection and fast dynamic response. Emerging trends include hybrid and adaptive algorithms that combine data-driven methods with physics-based models, as well as tailored solutions for small-scale and urban turbines where flow variability and structural constraints demand bespoke designs. Collectively, these strategies serve to maximise energy yield, reduce downtime and integrate wind power seamlessly into increasingly complex electrical networks.

Recent work has evaluated the performance of small wind turbines in urban environments, demonstrating that mechanical inertia can reduce energy yield by up to 25% under gusty conditions and that a pseudo-MPPT power conversion system can outperform full MPPT schemes by around 5% in rapidly varying winds. A comprehensive review of small-scale turbine control in high-speed wind regimes highlights the growing adoption of electrical stall control integrated with MPPT loops as a cost-effective alternative to pitch mechanisms, detailing various stall-mode strategies to safeguard turbines while maintaining energy capture. Advanced control for grid-connected systems has been explored through the development of a permanent magnet synchronous generator model with vector-control on the generator side and model predictive control for the grid converter, accompanied by a novel LCL filter design that simplifies parameter selection and enhances active and reactive power regulation under variable wind speeds.
