In this paper, the typical application scenarios of energy storage system are summarized and analyzed from the perspectives of user side, power grid side and power generation side.
At present, the cost–benefit analysis of energy storage in the literature is mostly based on the specific application scenario of a certain type of energy storage. Energy arbitrage, as the main source of income from energy storage, is often used as the benefit model to analyze the profits of energy storage [ 23 ].
The factors that influence the business model include peak–valley price difference, frequency modulation ratio of the market, as well as the investment cost of energy storage, so this paper will discuss from the following perspectives.
Combined with the energy storage application scenarios of big data industrial parks, the collaborative modes among different entities are sorted out based on the zero-carbon target path, and the maximum economic value of the energy storage business model is brought into play through certain collaborative measures.
In this case, the energy storage side connects the source and load ends, which needs to fully meet the demand for output storage on the power side and provide enough electricity to the load side, so a large enough energy storage capacity configuration is a must.
In the three scenarios, with the distinction between the two methods of energy storage capacity configuration, it is clear that the storage capacity of the energy with the surplus power online presents far less than with surplus power offline in local equilibrium.
In the context of China's electricity market restructuring, the economic analysis, including the cost and benefit analysis, of the energy storage with multi-applications is urgent for the market policy design in China.

Today, an estimated 4.67 TWh of electricity storage exists. This number remains highly uncertain, however, given the lack of comprehensive statistics for renewable energy storage capacity in energy rather than power terms.
Compressed air energy storage (CAES), although based on a combination of mature technologies, could see a 17% cost decline by 2030. Flywheels store energy as rotational kinetic energy by accelerating and braking a rotating mass. They have a high power potential.
Electricity storage is currently an economic solution of-grid in solar home systems and mini-grids where it can also increase the fraction of renewable energy in the system to as high as 100% (IRENA, 2016c). The same applies in the case of islands or other isolated grids that are reliant on diesel-fired electricity (IRENA, 2016a; IRENA, 2016d).
More directly, electricity storage makes possible a transport sector dominated by electric vehicles (EVs), enables efective, 24-hour of-grid solar home systems and supports 100% renewable mini-grids. As variable renewables grow to substantial levels, electricity systems will require greater flexibility.
As variable renewables grow to substantial levels, electricity systems will require greater flexibility. At very high shares of VRE, electricity will need to be stored over days, weeks or months. By providing these essential services, electricity storage can drive serious electricity decarbonisation and help transform the whole energy sector.
In transport, the viability of battery electricity storage in electric vehicles is improving rapidly. Batteries in solar home systems and of-grid mini-grids, meanwhile, are decarbonising systems that were heavily reliant on diesel fuel, while also providing clear socio-economic benefits.
Batteries can store energy from all sources of electricity, including renewables. For example, an 800 MWh battery energy system with a maximum capacity of 200 MW can deliver 200 MW for four hours, which typically can power up to 200,000 homes.
As of the end of 2022, the total nameplate power capacity of operational utility-scale battery energy storage systems (BESSs) in the United States was 8,842 MW and the total energy capacity was 11,105 MWh. Most of the BESS power capacity that was operational in 2022 was installed after 2014, and about 4,807 MW was installed in 2022 alone.
An energy storage system (ESS) for electricity generation uses electricity (or some other energy source, such as solar-thermal energy) to charge an energy storage system or device, which is discharged to supply (generate) electricity when needed at desired levels and quality. ESSs provide a variety of services to support electric power grids.
The major uses and benefits of ESSs are: Balancing grid supply and demand and improving quality and reliability —Energy storage can help balance electricity supply and demand on many time scales (by the second, minute, or hour).
Reducing end-user demand and demand charges —Commercial and industrial electricity consumers can deploy on-site energy storage to reduce their electricity demand and associated demand charges, which are generally based on their highest observed levels of electricity consumption during peak demand periods.
Home battery storage systems have revolutionized the way we manage energy consumption, providing homeowners with greater control over their usage, increased resilience to grid outages and fluctuating energy prices, and improved sustainability.
All other planned energy storage projects reported to EIA in various stages of development are BESS projects and have a combined total nameplate power capacity additions of 22,255 MW planned for installation in 2023 through 2026. About 13,881 MW of that planned capacity is co-located with solar photovoltaic generators.
