Abstract：To achieve effective integration of renewable energy and reduce the instantaneous power

fluctuations of wind power，a hybrid energy storage system（HESS）operation strategy and integrated capacity

allocation considering the smoothing of power fluctuation of wind farms was proposed by leveraging the

complementary characteristics of high-energy-density lithium battery storage and high-power-density flywheel

storage. Firstly，an energy management system for HESS that coordinates multiple energy storage systems was

constructed，taking into account constraints such as power capacity and charge-discharge efficiency. Additionally，

with the objectives of minimizing the comprehensive cost of the energy storage system and the opportunity

compensation cost of wind power，a baseline variable was introduced for correction to establish a capacity

configuration model for HESS that mitigates wind power fluctuations. Finally，by utilizing actual grid-connected

data，the optimal capacity configuration for the energy storage was obtained. The results show that this strategy

significantly reduces the grid-connected fluctuation rate while notably decreasing the configuration cost of the

energy storage system.
