This paper established a frequency characteristic model of a power system, including wind power and energy storage, and analyzed the influence of different frequency regulation methods on system stability.
[PDF Version]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.
Power system with wind power and energy storage. The frequency regulation model containing wind power and energy storage can be divided into primary frequency regulation, secondary frequency regulation, wind power regulation, and battery regulation. When a disturbance occurs, these regulation methods can be regulated individually or in combination.
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.
As of recently, there is not much research done on how to configure energy storage capacity and control wind power and energy storage to help with frequency regulation. Energy storage, like wind turbines, has the potential to regulate system frequency via extra differential droop control.
The participation of wind power and energy storage in frequency regulation can significantly improve the amplitude-frequency response gain of the power system. Wind power and energy storage can significantly suppress the disturbance gain in the frequency band below the fundamental frequency.
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.
Energy storage facilities are harnessed for peak shaving and frequency regulation purposes, skillfully storing surplus energy during low-demand periods and promptly releasing it when demand surges, thereby harmonizing the supply-demand disparity.

Energy storage configured in thermal power plants is mainly used to participate in peak and frequency regulation, which can not only make profits, but also alleviate the excessive coal consumption and serious equipment wear in power generation process [17, 18].
[PDF Version]A corresponding peak load regulation model is proposed. On the generation side, studies on peak load regulation mainly focus on new construction, for example, pumped-hydro energy storage stations, gas-fired power units, and energy storage facilities .
The peak load regulation problem causes challenges to the power system, and countermeasures are studied on the demand side and the generation side. On the demand side, demand response programs encourage consumers to reduce and/or shift their electricity usage during peak hours .
Some scholars have made lots of research findings on the economic benefit evaluation of battery energy storage system (BESS) for frequency and peak regulation. Most of them are about how to configure energy storage in the new energy power plants or thermal power plants to realize joint regulation.
Conclusion This paper presented an optimal scheduling model for power system peak load regulation considering the short-time startup and shutdown operations of a thermal power unit. As the main resource on the generation side, the intrinsic capacity of the thermal units in the system peak load regulation was studied in this paper.
For power units participating in deeper peak load regulation, the compensated electricity quantities are determined by regulation durations and the difference between the actual load rate and the lower bound of the basic regulation range. The compensation standards are under a set of piecewise progressive rules, as displayed in Table 3.
To the best of our knowledge, this study is the first to integrate different modes' peak load regulation cost of thermal units into the optimal scheduling model. The proposed method was verified in a real prefecture-level urban power system in southwest China, and its modified test systems.
Grid-Side Large Energy Storage System plays a critical role in the power system. By storing energy during low-demand periods and releasing it during peak times, it effectively balances power supply and demand, enhancing grid stability and reliability.
