This text explores how Battery Energy Storage Systems (BESS) and Virtual Power Plants (VPP) are transforming frequency regulation through fast response capabilities, advanced control strategies, and new revenue opportunities for asset owners. A reduced second-order model is developed based on aggregation theory to simplify the multi-machine system and facilitate time-domain frequency. With advanced technologies and expertise, HyperStrong offers a wide range of utility-scale energy storage solutions, which are designed to support a transition to a more sustainable and stable electricity system by integrating renewable energy resources, optimizing thermal power, and enhancing grid. Electrochemical energy storage participating in auxiliary grid frequency regulation has characteristics such as fast response speed, strong short-term power throughput capacity,. Key research gaps are identified, and future directions are outlined to promote more adaptive, control-oriented use of. This paper focuses on the flywheel energy storage array system assisting wind power generation in grid frequency regulation. Modern energy systems require increasingly sophisticated.
