Frequency of wind power storage

Existing frequency regulation methods have certain shortcomings: traditional frequency regulation units respond slowly; wind turbine frequency regulation is limited by its operating conditions and parameters; energy storage systems respond quickly and adjust. . Existing frequency regulation methods have certain shortcomings: traditional frequency regulation units respond slowly; wind turbine frequency regulation is limited by its operating conditions and parameters; energy storage systems respond quickly and adjust. . To address this issue, this study proposes a virtual inertia-based control strategy for hybrid wind–storage systems, formulated through transfer function modeling of wind turbines, thermal generators, and energy storage units. Although wind is abundant, environment-friendly, and cheap, it is variable in nature and does not contribute to system inertia as much as con-ventional synchronous generators.
