Chinese Application Scenarios and Study of Development Trends for New-type Energy Storage Technologies

In order to accelerate the construction of new-type power system with new-type energy as the main body and solve the problems of high proportion of new energy scale and large random fluctuation, China is actively promoting the large-scale application of new-type energy storage, so as to provide strong support for the green and low-carbon transformation of energy and the safe and stable operation of power grid. Firstly, this paper introduces the development status of new-type energy storage in China from the aspects of energy storage scale and energy storage application distribution; Secondly, the technology and economy of new-type energy storage are analyzed such as physical energy storage, electrochemical energy storage, electromagnetic energy storage, thermal energy storage, and chemical fuel energy storage; Then, the typical application scenarios of the new-type energy storage in the power supply side, power grid side and user side are proposed; Finally, the development route of Chinese new-type energy storage is analyzed and the corresponding development roadmap is given.
