What is Wind Turbine Control Systems?
Wind Turbine Control Systems are control strategies and technologies used to manage the operation of wind turbines, enabling integration of wind power into power systems through mechanisms such as doubly fed induction generators, power electronics, frequency control, variable speed operation, inertia emulation, maximum power tracking, and compliance with grid code requirements.
The field encompasses 30,535 works focused on integrating wind power into power systems using doubly fed induction generators, power electronics, and control strategies for grid stability. Key areas include grid code requirements, frequency control, variable speed turbines, inertia emulation, and maximum power tracking. These systems address the impact of wind power variability on power system stability.
Topic Hierarchy
Research Sub-Topics
Doubly Fed Induction Generator Control
This sub-topic develops vector control, stator flux orientation, and power decoupling for DFIG wind turbines using back-to-back converters. Researchers address LVRT and harmonic mitigation.
Wind Turbine Maximum Power Point Tracking
Studies optimize MPPT algorithms like tip speed ratio control, optimal torque, and hill-climb search for variable-speed operation. Perturb-and-observe methods handle turbine nonlinearities.
Wind Power Grid Frequency Control
Researchers design virtual inertia, droop control, and synthetic governors for wind farms to emulate synchronous generator frequency response. Emulation uses stored kinetic energy and energy storage.
Wind Farm Grid Code Compliance
This area analyzes requirements for fault ride-through, reactive power support, and power quality in standards like IEC 61400-27. Validation uses RTDS simulations and field tests.
Power Electronics for Wind Turbines
Investigations cover full-scale converters, NPC topologies, and SiC devices for PMSG and SCIG turbines. Focus includes efficiency, thermal management, and DC-link stability.
Why It Matters
Wind turbine control systems enable large-scale wind power integration into electrical grids, supporting grid stability through frequency control and inertia emulation amid variable wind speeds. For instance, R. Peña, John Clare, and G.M. Asher (1996) detailed a doubly fed induction generator (DFIG) using back-to-back PWM converters, achieving independent control of active and reactive power for variable-speed wind-energy generation, which reduces costs for turbines above 1 MW as shown by Sascha Müller, M. Deicke, and Rik W. De Doncker (2002). These controls meet grid code requirements outlined by Marina A. Tsili and Stavros A. Papathanassiou (2009), ensuring wind farms provide voltage and frequency support comparable to conventional generators. Applications span wind farms where power electronics, reviewed by Zhe Chen, Josep M. Guerrero, and Frede Blaabjerg (2009), optimize energy capture and grid compliance.

Frequently Asked Questions
What is a doubly fed induction generator in wind turbine control?
A doubly fed induction generator (DFIG) uses back-to-back PWM voltage-source converters in the rotor circuit for variable-speed wind-energy generation. R. Peña, John Clare, and G.M. Asher (1996) describe its vector-control scheme, which independently regulates active and reactive power from the supply. This setup allows speed adjustment over a wide range at minimal cost, as detailed by Sascha Müller, M. Deicke, and Rik W. De Doncker (2002).
How do power electronics support wind turbine control systems?
Power electronics in wind turbines enable control of generators and converters for grid integration and maximum power tracking. Zhe Chen, Josep M. Guerrero, and Frede Blaabjerg (2009) review topologies for various wind turbine systems, comparing features like variable speed operation. These converters handle frequency control and inertia emulation in wind farms.
What are grid code requirements for wind turbine control?
Grid codes specify technical requirements for wind farm connections to power systems, including voltage regulation and fault ride-through. Marina A. Tsili and Stavros A. Papathanassiou (2009) overview these requirements from transmission system operators in high wind penetration regions. Compliance ensures wind turbines support grid stability like conventional power plants.
How is control implemented in permanent-magnet generators for wind turbines?
Permanent-magnet synchronous generators (PMSG) in variable-speed wind systems connect directly to the grid via power electronics for control. Mónica Chinchilla-Sánchez, Santiago Arnaltes, and Juan Carlos Burgos (2006) describe operation with back-to-back converters regulating active and reactive power. This achieves maximum power tracking while maintaining constant grid frequency.
What role does energy storage play in wind turbine control?
Energy storage technologies support wind power applications by mitigating variability and aiding frequency control. Francisco Díaz‐González, Andreas Sumper, Oriol Gomis‐Bellmunt, and Roberto Villafáfila‐Robles (2012) review storage options for grid integration. These systems enhance inertia emulation and stability in wind-dominated grids.

Recent Trends
The field maintains 30,535 works with sustained emphasis on DFIG controls from foundational papers like R. Peña et al. (1996, 2739 citations) and power electronics reviews by Chen et al.
