Integrating energy storage systems (ESS) directly with wind farms has become the critical solution. However, successful wind farm energy storage integration is far more complex than simply adding batteries.
Existing research methods did not consider how to allocate shared energy storage among wind farm groups in the wind power base. This paper proposes an energy storage capacity allocation method for wind farm groups. Firstly, a bilevel model for the shared energy storage allocation is established.

How big are wind turbines and how much electricity can they generate? Typical utility-scale land-based wind turbines are about 250 feet tall and have an average capacity of 2.55 megawatts, each producing enough electricity for hundreds of homes. While land-based wind farms may be remote, most are easy to access and connect to existing power grids. Smaller turbines, often

Wind power has grown rapidly since 2000, driven by R&D, supportive policies and falling costs. Global installed wind generation capacity – both onshore and offshore – has increased by a factor of 98 in the past two decades, jumping from 7.5 GW in 1997 to 1 131 GW by 2024 according to IRENA''s data. Wind energy added 113 GW of new capacity in 2024 alone, growing by 11.1%

Abstract: Wind farms have large fluctuations in grid connection, imbalance between supply and demand, etc. In order to solve the above problems, this paper studies the capacity optimization configuration of wind farm energy storage system based on full life cycle economic analysis.
The CES operator can aggregate idle energy storage capacity and invest in a portion of centralized energy storage devices to provide energy storage leasing service. Wind farms can lease CES to suppress wind power fluctuations, which brings new problems of energy storage capacity configuration.
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.
Taking full account of the demand of wind farms to extend the service life of self-built energy storage and suppress wind power fluctuations, an optimization model of wind farm capacity configuration based on CES service is established. Through theoretical analysis and case studies, the following conclusions can be drawn:
Considering whole-life-cycle cost of the self-built energy storage, leasing and trading cost of the CES and penalty cost of wind abandonment and smooth power shortage, an optimal configuration model of combined energy storage capacity in wind farms based on CES service was established to minimize the total annual cost.
