The economic dynamics between fixed and mobile energy storage systems, as observed in the trends and annual cost compositions from 2020 to 2050, are influenced by advancements in technology, the increasing proportion of renewable energy, infrastructure capabilities, geographical distances between energy sources and load centers, and the high.
Mobile energy storage can improve system flexibility, stability, and regional connectivity, and has the potential to serve as a supplement or even substitute for fixed energy storage in the future. However, there are few studies that comprehensively evaluate the operational performance and economy of fixed and mobile energy storage systems.
Tech-economic performance of fixed and mobile energy storage system is compared. The proposed method can improve system economics and renewable shares. With the large-scale integration of renewable energy and changes in load characteristics, the power system is facing challenges of volatility and instability.
Fixed energy storage refers to energy storage equipment installed in a fixed position, which can improve the stability and reliability of the power system. Fixed energy storage has a large storage capacity and stability, suitable for long-term operation and can meet large-scale power storage needs.
As a flexible energy storage solution, mobile energy storage also shows a trend of decreasing technical and economic parameters over time. Like fixed energy storage, the fixed operating costs, battery costs, and investment costs of mobile energy storage also decrease with the increase of years.
Currently, energy storage systems are divided into fixed energy storage and mobile energy storage, both of which are suitable for different scenarios. Existing researches on energy storage operation and economy focus on fixed energy storage .
The total system cost of mobile energy storage is the same as that of fixed energy storage, including investment cost, operating cost, and recovery cost. Unlike mobile energy storage, which incurs transportation costs during energy transportation, fixed energy storage incurs line transportation costs during energy transportation.

Lead–acid batteries have been used for energy storage in utility applications for many years but it has only been in recent years that the demand for battery energy storage has increased.
Applications of lead-acid batteries in medium- and long-term energy storage While the energy density and cycling characteristics of Pb-acid battery technology are inferior to competing technologies, these are offset to a large degree by the low cost and high maturity level of the industry.
Lead batteries cover a range of different types of battery which may be flooded and require maintenance watering or valve-regulated batteries and only require inspection.
Periodically fully charging a lead–acid battery is essential to maintain capacity and usability. In traditional UPS or cyclic use, full recharge normally occurs following any discharge. This is in contrast to partial-state-of-charge use. In this use case, multiple shallow cycles of less than 50% of the battery capacity occur before a full charge.

Lead batteries are very well established both for automotive and industrial applications and have been successfully applied for utility energy storage but there are a range of competing technologies including Li-ion, sodium-sulfur and flow batteries that are used for energy storage.
Each battery is grid connected through a dedicated 630 kW inverter. The lead–acid batteries are both tubular types, one flooded with lead-plated expanded copper mesh negative grids and the other a VRLA battery with gelled electrolyte.

Li-ion and other battery types used for energy storage will be discussed to show that lead batteries are technically and economically effective. The sustainability of lead batteries is superior to other battery types.
