It also introduces the application scenarios of energy storage on the power generation side, transmission and distribution side, user side and microgrid of the power system in detail. Section 3 introduces six business models of energy storage in China and analyzes their practical applications.
Energy storage projects in North China are currently the most in China. Due to the geographical environment, the power grid in Northwest China cannot supply power to all regions. Provide electricity to the people of the region through off-grid distributed generation and energy storage systems.
With the advancement of battery technology, such as increased energy density, cost reduction, and extended cycle life, the economy of mobile energy storage systems will be further improved. Future research should focus on the impact of new technologies on system performance and update model parameters in a timely manner.
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.
In terms of mobile energy storage, Northeast China has a unit capacity absorption ranging from 30 kWh to 90 kWh, compared to 15 kWh to 56 kWh in North China. (2) As the share of renewable energy in the system increases, the absorption capacity of fixed energy storage initially rises and then declines, with 50% and 55% as the inflection points.
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.
