Integrating wind power with energy storage technologies is crucial for frequency regulation in modern power systems, ensuring the reliable and cost-effective operation of power systems while promoting the widespread adoption of renewable energy sources.
The energy storage system can increase and decrease the output flexibly, which can improve the frequency regulation characteristics of the power system with wind power. Therefore, wind farms can build energy storage power stations with a certain capacity and undertake the task of frequency regulation.
This manuscript provides a strategy for energy storage to coordinate wind farms to participate in primary frequency regulation of power system, and compares three frequency regulation schemes of wind power reserve, rotor inertia control and wind farm with energy storage. The comparison results show that: Wind power reserve is the least economic.
The energy storage capacity configuration and wind/storage coordinated control strategy proposed in this paper based on the system frequency regulation requirements significantly improves the frequency support performance of wind power generation system. 6. Conclusion
In the power systems with high proportion of renewable power generation, wind turbines and energy storage devices can use their stored energy to provide inertia response and participate in primary frequency regulation for the improved system frequency stability.
Results from [ 7] show that some wind energy is wasted during the frequency regulation process because the wind turbine can only use the energy stored in the rotor. Energy storage systems are applied to wind farms to help maintain the frequency stability of the system after wind power is connected to the power system.
In view of the frequency problem caused by the large-scale grid connection of wind power, this chapter proposes to use energy storage and wind turbines to cooperate with traditional thermal power plants to participate in power system frequency regulation,, .

[PDF Version]At present, China's small capacity energy storage power stations cannot be allowed to compete for frequency regulation services, but the establishment of auxiliary service markets such as frequency regulation and standby is conducive to guiding investment to improve the flexibility of power systems [ 19, 20, 21, 22, 23, 24, 25 ].
The main contributions of this work are described as follows: A peak shaving and frequency regulation coordinated output strategy based on the existing energy storage participating is proposed to improve the economic problem of energy storage development and increase the economic benefits of energy storage on the industrial park.
Therefore, the energy storage power station is equipped with energy storage battery for peak shaving, which has limited savings on electricity charges. This is because if the energy storage output is small and the peak shaving is small, it has little impact on electricity charges.
Therefore, the economic benefits of user-side energy storage participating in frequency regulation can improve the economy of user equipped energy storage.
According to the capacity planning model of peak shaving and frequency regulation and the parameters given above, an energy storage battery with a maximum power of 1 MW and capacity of 1 MW·h was used to carry out the day-ahead peak shaving and frequency regulation planning on the user side. The obtained results are E1 = 0.8 MW·h and E2 = 0.2 MW·h.
