As shown in Figure 1, the supercapacitor is mainly composed of many parts, like current collectors, electrodes, electrolytes, and separators. The role of the separator has the same function as the separator in the battery. It isolates the two electrodes to prevent short circuit between the electrodes and allows ions to pass. There are many materials used in the manufacture and production of supercapacitor electrodes and electrolytes. In order to deeply understand the energy storage. There are many classification standards for the supercapacitors. This article will mainly introduce two classification methods. The first one will be classified according to the different energy storage mechanisms of the electrode materials, and the second one will be.

Heat storage — storing solar energy directly as thermal mass rather than converting it to electricity and back — is 5 to 10 times cheaper per kWh of storage capacity than battery storage, lasts indefinitely, and requires no electronics, BMS, or inverter. The trade-off: you can only use the stored. Thermal storage technologies have the potential to provide large capacity, long-duration storage to enable high penetrations of intermittent renewable energy, flexible energy generation for conventional baseload sources, and seasonal energy needs. Thermal storage options include sensible, latent. To eliminate its intermittence feature, thermal energy storage is vital for efficient and stable operation of solar energy utilization systems. It is an effective way of decoupling the energy demand and generation, while plays an important role on smoothing their fluctuations.

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 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.

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.

Each thermal energy storage technology has its advantages and disadvantages as shown in Fig. 2. LTES has the advantages of comprehensive large energy storage density, compact in size and high technical feasibility to be used for renewable energy storage, waste heat recovery (WHR) and thermal power buffering in industrial processes.
Thermal energy storage (TES) is the storage of thermal energy for later reuse. Employing widely different technologies, it allows surplus thermal energy to be stored for hours, days, or months. Scale both of storage and use vary from small to large – from individual processes to district, town, or region.
Using heat pumps or electric boilers as examples, thermal energy storage is far more cost-effective than electricity storage and offers great promise for integrating variable renewable energy sources like wind and solar into the heating and cooling industry.
1. Thermal energy can be easily converted into other forms of energy such as mechanical, electrical, or chemical energy, making it versatile for various applications. 2. Thermal energy is abundant and widely available from natural sources such as sunlight, geothermal heat, and waste heat from industrial processes.
Thermal energy storage systems collect and store heat from renewable sources like solar or geothermal for later use. For example, storage of solar thermal energy involves capturing the sun's rays and using them to warm a fluid or a phase change material, which may then be used to heat a building's interior or a water supply.
High installation costs: Building and maintaining thermal energy storage systems can be expensive, making it a barrier for many individuals and businesses. These costs include not only the initial investment but also the ongoing maintenance and operation expenses.
