Energy storage mobile power supply in developed countries

Is mobile energy storage a viable alternative to fixed energy storage?

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.

Can a fixed and mobile energy storage system improve system economics?

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.

Why is mobile energy storage important?

Therefore, enhancing the safe and stable operation capability of the power system is an urgent problem that needs to be solved. 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.

What are the development directions for mobile energy storage technologies?

Development directions in mobile energy storage technologies are envisioned. Carbon neutrality calls for renewable energies, and the efficient use of renewable energies requires energy storage mediums that enable the storage of excess energy and reuse after spatiotemporal reallocation.

What is the absorption capacity of mobile energy storage in China?

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.

What is the economics of mobile energy storage?

Under the medium renewable energy permeability (such as 44% and 58%), the economics of mobile energy storage is comparable to that of fixed energy storage, which is reduced to 2.0 CNY/kWh and 1.4 CNY/kWh.
