Abstract: The penetration of renewable energy in power systems continues to increase, wind-storage hybrid systems play a crucial role in maintaining grid frequency stability. This paper systematically reviews major research advancements in areas such as inertia response and primary frequency regulation, coordinated control of doubly-fed induction generators (DFIGs) with synchronous generators, virtual synchronous generator (VSG) technology, energy storage capacity optimization, and adaptability in high-penetration grids. Various control strategies are summarized in terms of their application effectiveness for frequency support, economic efficiency, and adaptability. Firstly, the paper discusses the application of inertia response and primary frequency regulation strategies, including methods like virtual inertia and pitch angle control, and their effectiveness in frequency support. Secondly, it explores the advantages of DFIG and synchronous generator coordinated control and VSG technology for frequency stability. Next, it examines achievements in enhancing the frequency regulation efficiency and economic performance of energy storage systems through multi-objective optimization and capacity configuration. Finally, the adaptability of wind-storage systems in high-penetration grids is analyzed, with a focus on the application of grid-forming control, distributed control, anyyd other strategies in complex grid environments. This paper provides systematic theoretical support and technical references for the practical application of wind-storage hybrid systems in high-penetration grids, contributing to the future construction of a stable and efficient modern power system.
