This study offers valuable insights into designing the configuration and operational strategy of a renewable energy-coupled hydrogen energy storage system, along with guidance for optimizing its multi-objective capacity allocation.
For capacity allocation, the capacity of energy storage equipment determines its ability to effectively stabilize wind power fluctuations. In particular, the battery''s life attenuation, caused by cycle aging and calendar aging, can affect its long-term wind power smoothing ability.
Based on the actual operating data of a wind farm in Inner Mongolia, the amplitude frequency characteristics were analyzed, and a hybrid energy storage system w
Optimal storage capacity for wind energy is determined by various factors including energy demands, technological capabilities, and geographical considerations.
The newly added installed capacity of wind storage is calculated by changing the access location and access amount of three kinds of equipment, namely "wind", "photovoltaic" and "energy storage".
Let''s cut through the noise: when we talk about the storage capacity of wind farms, we''re really asking how to bottle lightning. Well, not literally – but storing wind energy is almost as tricky.
Considering the economic benefits of the combined wind-storage system and the promotion value of using energy storage to suppress wind power fluctuations, it is of great significance to study the optimal allocation of energy storage capacity for wind farms.

Because power systems are balanced at the system level, no dedicated backup with energy storage is needed for any single technology. Storage is most economical when operated to maximise the economic benefit of an entire system.
With the development of energy storage technology, it is more efficient to connect wind turbines with storage devices, which can efficiently store the energy produced by wind turbines, and play a crucial role in optimizing the efficiency and reliability of wind energy.

The allocation of power governs the specific power delivered by each individual energy storage unit, while the distribution of storage capacity is determined by the capabilities of the power storage system.
The integration of wind power storage systems offers a viable means to alleviate the adverse impacts correlated to the penetration of wind power into the electricity supply. Energy storage systems offer a diverse range of security measures for energy systems, encompassing frequency detection, peak control, and energy efficiency enhancement .

Mainstream wind power storage systems encompass various configurations, such as the integration of electrochemical energy storage with wind turbines , the deployment of compressed air energy storage as a backup option , and the prevalent utilization of supercapacitors and batteries for efficient energy storage and prompt release [16, 17].
Wind and hydrogen energy storage systems are increasingly recognized as significant contributors to clean energy, driven by the rapid growth of renewable energy sources. To enhance system efficiency and economic feasibility, a model of a wind power-integrated hybrid energy storage system with battery and hydrogen was developed using TRNSYS.
Additionally, from the standpoint of capacity allocation, the battery's service life can be reasonably estimated according to its life attenuation mechanism, and the energy storage capacity allocation that meets the wind power smoothing requirements can be achieved in combination with the economic cost analysis.
Moreover, the overall load exhibits fluctuations ranging from 15 to 72 MW, while the average load remains consistently around 41 MW. This finding implies that the daily load ratio achievable by the distributed wind power storage system can reach 71%.
