Energy storage technologies has both the power supply capacity and the power storage capacity, so the power of energy storage technologies includes the supply power and the storage power , and both of them are nonnegative and no more than the installed capacity for any energy storage technology in planning periods of power areas .
Energy storage technologies are growing fast and in high demand, Figure 1 demonstrated the installation and growth rate curves for electrochemical energy storage in China. New-type of energy storage mainly refers to energy storage technologies other than pumped storage.
According to relevant calculations, installed capacity of new type of energy storage in the first 4 months of 2023 has increased by 577% year-on-year. By 2030 the installed capacity of new type of energy storage will reach 120 GW and will reach to 320 GW by 2060. Installation and growth rate curves for electrochemical energy storage in China.
In this case analysis, the installed capacity and energy capacity of energy storage technologies are illustrated in Table 2. PHS or CAES have the priority in expansion planning as they have the cost advantage, and BES can only be configured in scientific research, demonstration application, frequency and voltage regulation, etc.
The installed capacity is expected to exceed 100 GW. Looking further into the future, breakthroughs in high-safety, long-life, low-cost battery technology will lead to the widespread adoption of energy storage, especially electrochemical energy storage, across the entire energy landscape, including the generation, grid, and load sides.

Considering the flexible potential and cost factors, the capacity of energy storage equipment can be reasonably determined in accordance with SSES and SES. The capacity of electricity storage equipment is closely related to the installed capacity of a renewable energy system.
The capacity of electricity storage equipment is closely related to the installed capacity of a renewable energy system. Presenting a PV power generation system as an example, the installed capacity of PV power generation and the storage capacity of the battery must match each other.
Firm Capacity, Capacity Credit, and Capacity Value are important concepts for understanding the potential contribution of utility-scale energy storage for meeting peak demand. Firm Capacity (kW, MW): The amount of installed capacity that can be relied upon to meet demand during peak periods or other high-risk periods.
The maximum amount of energy accumulated in the battery within the analysis period is the Demonstrated Capacity (kWh or MWh of storage exercised). In order to normalize and interpret results, Efficiency can be compared to rated efficiency and Demonstrated Capacity can be divided by rated capacity for a normalized Capacity Ratio.
Under the MPFPH situation, the minimum electricity storage capacity can ensure the maximum flexible potential during the peak period of electricity consumption. Moreover, storage capacity is relatively large, and thus, it can also prevent the occurrence of the light abandonment phenomenon.
In addition, the capacity of heat storage equipment is directly related to the number of energy storage times. For example, the energy storage equipment is required to have a large capacity to store the cold/heat required for 1 day at one time (single-stage energy storage, SSES) during the valley power consumption period.

PVT refers to solar thermal collectors that simultaneously produce electrical and thermal energy using PV cells integrated into the absorber plate.
Applications of photovoltaic–thermal systems are summarized in detail. A view on the future of PV/T developments and the future work is presented. The commercial solar cells are currently less efficient in converting solar radiation into electricity. During electric power convention, most of the absorbed energy is dissipated to the surroundings.
Because more than 80% of renewable power energy is converted to heat, that can harm PV cells if not stored in a thermal collector (Diwania et al., 2020). The concept of PVT system is depicted in Fig. 2. The solar PVT system converts solar energy into both electrical and thermal energy.
Herez et al. (2020) pointed out that in comparison to other PV cells, crystalline silicon, and InGap/GaAs/Ge triple-junction solar cells are commonly applied in PVT systems.
Photovoltaic and thermal (PVT) energy systems are becoming increasingly popular as they maximise the benefits of solar radiation, which generates electricity and heat at the same time.
Photovoltaic integrated with thermoelectric cooler (PV/TEC) systems Compared with single solar PV or solar thermal systems, PV/T system provides a higher total energy output including thermal energy output and electrical energy output. However, the majority of the overall energy is in thermal form, which is a low-grade energy .
