Abstract:

With the clear goal of carbon neutralization, new energy will gradually become the pillar energy of power system. Facing the characteristics of high proportion of renewable energy and high proportion of power electronic equipment in the power system, the difficulty of real-time power supply and demand balance will further increase. As the main way to improve the quality of new energy generation and stabilize the fluctuation of power grid, advanced energy storage technology has attracted much attention, but it is difficult to realize large-scale promotion due to economic constraints. The mobile energy storage system with high flexibility, strong adaptability and low cost will be an important way to improve new energy consumption and ensure power supply. It will also become an important part of power service and guarantee in the new power system in the future. Firstly, this paper combs the relevant policies of mobile energy storage technology under the dual carbon goal, analyzes the typical demonstration projects of mobile energy storage technology, and summarizes the research status of mobile energy storage technology, in order to provide reference for the multi scene emergency application of mobile energy storage technology; Then, based on the application scenario characteristics and demand analysis, the mobile energy storage technology index system is established, and the dynamic game adjustment method of mobile energy storage system cluster based on event and power regional characteristics is constructed according to the construction principle of mobile energy storage cooperation platform; Finally, combined with the double carbon goal and the demand of new power system, the application of mobile energy storage system technology is summarized and prospected.

Key words: mobile energy storage system, demonstration project, technical indicators, intelligent dispatching technology, scenario application
