New control strategy boosts wind turbine grid stability 2x

Conventional grid-forming control often treats the DC source as unconstrained, creating mismatches when applied to wind turbine generators. A new strategy coordinates primary frequency regulation with grid-forming control by linking the power-tracking coefficient, power set-point, and frequency deviation. This allows grid-forming wind turbines to consistently support frequency within predefined limits while maintaining appropriate power points and using allowable power reserves. The approach preserves the structure and dynamic performance of conventional grid-forming control and adapts to varying wind speeds. Comparative case studies under different operating scenarios show the strategy is effective and superior.
