Comprehensive evaluation index performance table. Therefore, in the current rapidly developing new energy landscape where conventional frequency regulation resources are insufficient, the proposed strategy allows for more economical and efficient utilization of energy storage to support the frequency regulation of thermal power units.
With the gradual increase of energy storage equipment in the power grid, the situation of system frequency drop will become more and more serious. In this case, energy storage equipment integrated into the grid also needs to play the role of assisting conventional thermal power units to participate in the system frequency regulation.
Aiming at the problems of low climbing rate and slow frequency response of thermal power units, this paper proposes a method and idea of using large-scale energy storage battery to respond to the frequency change of grid system and constructs a control strategy and scheme for energy storage to coordinate thermal power frequency regulation.
the integrated regulation strategy proposed in this paper determines the switching time and operating depth of the energy storage system and the flexible load, and makes rational and effective use of the frequency modulation resources to regulate, giving full play to their respective advantages.
When the energy storage system must be charged under the condition of frequency regulation, the charge power absorbed by the energy storage system steadily decreases when the SOC is at a high boundary value, and it eventually cannot absorb the charge power when the SOC hits the critical value.

The objective of thermal protection is to decrease or shift the heating/cooling load of a system, while the objective of an energy storage system is to store the thermal energy released from the system on demand [215, 221, 222].
Thermal energy storage (TES) systems store heat or cold for later use and are classified into sensible heat storage, latent heat storage, and thermochemical heat storage. Sensible heat storage systems raise the temperature of a material to store heat. Latent heat storage systems use PCMs to store heat through melting or solidifying.
Thermal energy storage units are mostly employed to sustain the operations more smoothly for night and daytime. The system with the most irreversibility presence is the molten salt thermal storage with an entropy generation value of 0.7044 kW/K, and the lowest value is 0.0054 kW/K for the PHES system.
The kinds of thermal energy storage can be divided into three separate categories: sensible heat, latent heat, and thermo-chemical heat storage. Each of these has different advantages and disadvantages that determine their applications. storage (SHS) is the most straightforward method. It simply means the temperature of some medium is either increased or decreased. This type of storage is the most commercially availabl.
