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.
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.
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.
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.
Based on BESSs, a mobile battery energy storage system (MBESS) integrates battery packs with an energy conversion system and a vehicle to provide pack-up resources [ 2] and reactive support [ 3] for disaster conditions, or to perform market arbitrage [ 4] in distribution networks.
In order to effectively absorb wind power by using local fixed energy storage, long-distance ultra-high voltage transmission is required to transmit “green power” to the load center. The disadvantage is high investment cost and low renewable energy transmission efficiency .
